2 INFRARED SPECTROSCOPY mind is that a successful interpretation is based not only on the presence of particular bands within the spectrum, but also the absence of other important bands.
Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. (Note that while individual C-H stretches are weak because of small changes in the dipole moment, a typical molecule often has a lot of these bonds, which makes these absorptions appear fairly intense.)

C–H stretch from 3000–2850 cm-1 thats the big one you see C–H bend or scissoring from 1470-1450 cm-1 C–H rock, methyl from 1370-1350 cm-1

Note the two features of the spectrum — the C-H absorptions between 2,800 cm–1 to 3,000 cm–1, and the fingerprint region below 1,500 cm–1. Resnik, Edith Gong, E.L. Pippen, David A. Forss. Recognizing where the absorptions generated by the common functional groups occur will help you to interpret IR spectra. Different functional groups produce bond absorptions at different locations and intensities on the IR spectrum. Fred Stitt, Robert B. Seligman, F.E.
