Can you give more details please

Thanks for your response. The compound consists of some particles (organic / inorganic) which was kept immersed in ethanol. This compound was subjected to FTIR study and got the above said peak values. When the peak values were compared with IR chart there was no correlation with the two.

Is your wavenumber range on the xaxis calibrated correctly?

Dear Lakshmi,

please specify what exactly you want to do with the sample? identification of any functional group?, determination of any compound? identification of any compound? reaction / process monitoring?

FTIR is good only for functional group identification if the compound is unknown. also the table value will not match with your compound as many factors will affect the vibrational frequency of your analyte.

please specify the compound name.

Selvan

also the FTIR will detect only the polar compound; FT Raman can be used for nonpolar compounds (alkanes)

FTIR region can be divided into functional group region and finger print region, functional group region can be used to identify the functional group of compound and finger print region can be used for identification of synthesized compound with standard.

Your result indicates the wetness of the sample it has to be very dry as u cud see a peak at 3853 cm-1 other then that or compound has primary amine shift and secondary amine as u cud observe 1650 range and 1550 range other than some thiols and alcoholic or carboxylic groups comes into play... we may want to take a look at the spectrum to predict it precisely

It is imperative to show the FT-IR spectrum image, signal width and intensity can't be guessed only through a simple signal report. Also, many functional groups will absorb in IR at a range of wavenumbers rather than at a single precise wavenumber.

Dear Lakshmi,

FTIR analysis is not suitable for inorganic compound, but your sample preparation excel that your compound have some organic & inorganic in ethanol.FTIR have divided  in two region functional group , fingerprinting region. If you are interested in inorganic ion ..your some peak gives presence of inorganic ion.

This book help you.

plz if someone has ir chart.. plz send me..

See the following link for a professional interpretation of FTIR data

To interpret FTIR results, you should first identify the functional groups by examining the peaks on the spectrum. You can compare the spectrum to a reference spectrum to determine the identity of the compound or compounds in your sample. Each peak corresponds to a particular vibrational mode in a molecule, and analyzing the position and shape of the peaks can provide information about the identity and structure of the compound. It is also important to consider the overall shape of the FTIR spectrum and interpret the results in the context of the specific experiment or analysis being performed. By following these steps, you can effectively interpret the FTIR results and gain a better understanding of the sample being analyzed.

Dear Ali Sonas

I used the interpretation service of the website that you introduced.

It was very good

I suggest the website to other researchers:

Thank you dear Ali

Fist of all FTIR spectroscopy provide bands, not peaks. And if you please provide the chemical details of the sample glady I could give you a preeliminar band assignment. Best regards. Hiram
