HOW TO READ AN IR SPECTRUM?
IR spectroscopy is sometimes known as "The functional group spectroscopy" because it gives us an idea of which functional groups are present in the molecule.
IR spectrum contains peaks for both stretching and bending vibrations and mostly these are the stretching vibration bands that diagnose the molecule, howevers sometimes the bending vibration bands are also needed for identifiction of certain functional groups.
This video is the first in this series and here we are discussing the carboxylic acid functional group.
