Some of the instrument softwares (e.g. spectrum=perkin elmer) have their own library to interpret spectra. However, note that analyst is the most important factor in spectral interpretation.

"I want to know the exact functional groups for my FTIR Spectrum" This is an art, where you require previous knowledge of your compound and previous knowledge on IR spectroscopy..

Most vendors will provide spectral interpretation packages, but for a full interpretation you need to do it yourself. It is an art and takes effort to develop interpretation skills. Being provocative, IR spectroscopy contains the most information of all spectroscopies as it has chemical and physical data. Unfortunately due to overlapping bands and ambiguities fundamental interpretation of IR (and Raman) spectra is becoming a lost skill and is not a trivial excercise.

For a complete unknown I will often run a library search just to mkae sure my initial assessment of the key functional groups is correct, then I get out my text books to complete the interpretation. My favourites are:

Infrared and Raman Characteristic group frequencies by George Socrates

Infrared and Raman characteristic frequencies of organic molecules by Lin-Vien, Colthup, Fateley and Grasselli

If you are new to IR interpretation, get yourself a mentor who can help you or find a spectral interpretation course to introduce you to the fundamentals.

it may help to interpret your FTIR spectrum.

Try 'FTIRsearch.com', its a Thermo-Scientific extension of the search capabilities found in the Omnic software search libraries

I agree with Teodoro S Kaufman and Donald A Clark, that it is an art and you need to do it yourself based on previous knowledge of your sample and previous studies on material similar to your sample

yes its available in online

Nice madam... Excellent and I do appreciate Golnaz Jozanikohan  for her valuable information useful for students world... 

Thank you very much for these valuable attached file Mr. Shabana Ahmed.

All the best 

I am working on cysteamine coatede gold nanoparticle and then immoblized an antibody for cancer but I have problem with FTIR analysis, which bond must be in my final product (antibody immoblized to cysteamine capped gold )or which peak must be in my diagram??

Hello,

you can download Specamp Software and use it to define all characteristic bounds with help of functional groups in its library . 

N.B: your IR spectral should be saved as file.DX to allow their manipulation.

Hello,

I used the Essential FTIR software to characterize the functional groups.

The latest version of Essential FTIR is 3.50. Click on the link below to start the download (about 22.3 MB).

very useful, thanks all.

the color of material is black ,i want to know if the FTIR will give good result or not ,my material is a reinforced SBR will black carbon , can I trosformed to solution to use FTIR ? and in many article i found the word pyrolyse related to rubber when they use FTIR , is it a transformation of rubber to solution (liquid)?

Thanks

Three best articles for interpreting FT-IR spectra

Thankyou all

VERY INTERESTING

Thank you Chandana and Maher for your nice informations.

THANK YOU

Thank you ALL who contributed in this section.

Thank you Golnaz Jozanikohan

I used the Essential FTIR software to characterize the functional groups.

May I know if the software shows the name of functional groups @Nowres Jaber? I have installed the software but I can't see any info about such detailed analysis.

We at VibSpec are developing software IRIS to support the process of interpreting vibrational spectra (IR and Raman). Prof. van der Maas started this software platform more than 30 years ago and we are updating it every year. You can test the fully functional software 15 days for free (https://www.vibspec.com/bv/vibspec_iris.html). It allows to import your spectrum (JCAMP-DX) and to get suggestions by clicking the peaks.

Thanks for all

The IR spectrum can be segregated into four regions. The first region ranges from 4,000 to 2,500. The second region ranges from 2,500 to 2,000. The third region ranges from 2,000 to 1,500. The fourth region ranges from 1,500 to 400.

Determine the functional groups absorbed in the first region. If the spectrum has a characteristic peak in the range of 4,000 to 2,500, the peak corresponds to absorption caused by N-H, C-H and O-H single bonds.

Determine the functional groups absorbed in the second region. If the spectrum has a characteristic peak in the range of 2,500 to 2,000, the peak corresponds to absorption caused by triple bonds.

Determine the functional groups absorbed in the third region. If the spectrum has a characteristic peak in the range of 2,000 to 1,500, the peak corresponds to absorption caused by double bonds such as C=O, C=N and C=C.

Compare the peaks in the fourth region to the peaks in the fourth region of another IR spectrum. The fourth is known as the fingerprint region of the IR spectrum and contains a large number of absorption peaks that account for a large variety of single bonds. If all the peaks in an IR spectrum, including those in the fourth region, are identical to the peaks of another spectrum, then you can be assured that the two compounds are identical.

Such great useful answers, thanks!

THANK YOU FOR ALL .MAY I HELP TO INTERPRET MY SAMPLE FTIR SPECTRUM, I DO KNOW HOW TO IDENTIFY MY RESULT.

Thanks Peter De Peinder. Will try this one.

Great amount of details and support links from all others.

Following...

dear friend one of my Ph.D student conducted a experiment for green synthesisis of silver nano particle in Momordica cymbalaria and she got one FTIR spectrum with this values 605.75;879.48;1048.89;1384.61;1607.08;2850.66;2920.30;3414.42;3789.0 CM-1. Hence i request you to give analysis of above graph (compounds and functional groups)

thanking you

Sir

From GC-MS analysis compounds can be identified but regarding functional groups I will let you know the functional groups of FT-IR analysis.

These PDF will help you out in FTIR analysis

I would like to recommend ACD/lab.

Thank you so much

Keenly interested

Very interesting

Thank You All to answer the query.

I am keenly interested but i can access the file hoe do i go about it

Thank you for your suggestions in the analysis of FTIR spectrum

Golnaz is correct

https://books.google.az/books?id=Ywzf4GyoUaoC&pg=PP9&lpg=PP9&dq=How+to+interpret+my+FTIR+spectrum?+Is+there+any+online+software+available+to+interpret+the+spectrum?&source=bl&ots=C5WLF18LF4&sig=ACfU3U1j4lgpCnbg8ZbtULkTIjUUvNPt9A&hl=ru&sa=X&ved=2ahUKEwjX4eLqoaTqAhVJyaQKHX7cDUoQ6AEwCnoECAcQAQ#v=onepage&q=How%20to%20interpret%20my%20FTIR%20spectrum%3F%20Is%20there%20any%20online%20software%20available%20to%20interpret%20the%20spectrum%3F&f=false

Interpretation of FTIR spectrum: You can see table of IR absorbance frequencies i.e. wave number(v)in cm-1.See the peaks above 1600cm-1 is group frequency region & below 1600cm-1 is the finger print region.Depending upon peak position in cm-1 one can find out the presence of functional group looking at the table values..

https://www.effemm2.de/spectragryph/index.html

I have used spectragraph software to analyzed the FTIR spectrum.

Yes. from the results you will be getting 2 graphs. one is standard data or reference data , the other one is your sample data.

you have to say in terms of percentage match with the reference graph. higher the percentage match that qualifies your sample. importantly you have mention which standard that you have used.

Be really careful with % match values -Yes, use as a guide but always compare your spectra with those in the library and check that the identification is correct. And challenge the library spectrum identity - there are errors in some commercial libraries which can lead to incorrect identifications.in commerci

In addition to the points mentioned by Donald A Clark, do not forget that absorbance derived from transmittance measurements might be different from those from ATR measurements, transflection etc (if you wonder why, see Article The Bouguer-Beer-Lambert Law: Shining Light on the Obscure

following

READ this paper

Be careful when you choose the correct X-axis & Y-axis. The X-axis of an IR spectrum called the Wavenumber and ranges in from 400 to 4000 from left to right. percent of transmittance can be found from the the Y-axis. Absorption of the material derived from the transmittance. You can interpret the FTIR graph using the table that contain with the functional groups.
