Dear everyone,

I am working on a project to measure the peptide bonding conformation. The first target is Insulin. I run the FTIR, and get a peak at ~ 1650 cm-1. I believe it is alpha-helix. But question is what the tiny peaks before (1450 - 1550) and after ( 1700 - 1850)the main peak can be assigned? Any suggestion is welcome.


Thank you for your help.
