Yes it does! You need to have an idea about your material so you can assign the vibration modes that you are seeing with the bonds/deffects that are generating the peak!
Sethuraj Geetha . Let me answer by another question:
"This morning I looked out of window and saw three flying birds. Does it have any significance?"
Stan Sykora
actually this is my first work on ft ir. As far as i have studied, the finger print region of FT IR, usually was supposed to be a very complicated series of absorptions, due to all manner of bending vibrations within the molecule. but in our case, only 3-4 peaks were seen. thats my doubt.
Ok Sethuraj. I was a bit kidding because the your query was practically without any details. It is hard to answer such queries. In particular you say nothing at all about your sample; try to imagine how many choices that leaves open. If it was some organic stuff, than you might be justified to wonder; but in general not. In general, at least a sample specification and, if possible, a shot of the actual spectrum, are a must for a meaningful answer.
Thank you Mr. Stan Sykora . awaiting your valuable guidance and suggestion
Your search results gave you the answer. It is a simple alcohol, probably methanol. But I will bet you collected the spectrum as ATR and did not correct it. In the ATR technique, the depth of penetration is wavelength dependent so that the absorbances at longer wavelengths are enhanced in comparison to the ones at the shorter wavelength. How you collect the data will impact the appearance of the spectrum and you need to take that into account. I might suggest that if you intend to attend SciX in the fall, you make use of the courses that the Society for Applied Spectroscopy (SAS) will be teaching there. This set will all be related to vibrational spectroscopy.
