Add to ORKGThe Raman and ir spectra of a-helical polybglutarnic acid) have been assigned on the basis of a normal mode calculation for this structure. The force field was based on our previously refined mainchain force constants for a-polyb-alanine) and side-chain force constants for /3calcium-poly(L-glutamate). Despite the identical backbone a-hel-ical structures, significantly different frequencies are calculated, and observed, in the amide I11 and backbone stretch regions of a-poly(L-glutamic acid), as compared with a-poly(L-alanine). This clearly demonstrates the influence of side-chain structure on main-chain vibrational modes
