Of recent I’ve been  trying to analyze some FT-IR spectra for my research on plasma and have been facing trouble trying to figure out which peaks correspond to what groups.
Luckily I came across this great tool which lists possible bonds that correspond with wave numbers which you can enter. It even has an option to perform a comprehensive search if you’re looking for a broader range of possibilities.
Want to study surface analysis? Here’s an excellent forum with details on techniques along with some very nice tutorials.
