Answer #1

The region to the right side of the diagram (from about 1500 to 500 cm-1) contains very complicated peaks . These are mainly due to all possible vibrations within the molecule. This is called the fingerprint region.

It is difficult to pick out individual bonds in this region than it is in the "cleaner" region at higher wavenumbers. The importance of the fingerprint region is that each compound produces a different pattern of troughs in this part of the spectrum. Specific to each molecule.

I obtained an IR spectra of low denisty polyethylene (top spectra) and then i heated at 320 C for 40 min and obtained the bottom spectra. Can someone help me label those peaks? Why was there an emergence of a new peak when it was burned? There was also one peak that dissapeared. Can someone explain it to me? here is the pic http://imgur.com/reHx5sP
