Vibrational analysis of conformation in peptides, polypeptides, and proteins This is paper number 16 in a series of which Ref. 20 is paper 15.

A vibrational force field for the polypeptide chain has been developed for normal-mode analysis of such molecules. It can reproduce observed frequencies of known structures to within about 5 cm −1 . We review the application of this technique to conformational problems in peptides (Β-turns and their model compounds), polypeptides [the Α II -helix and crystalline poly(glycine II)], and proteins (bacteriorhodopsin and glucagon).Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/37845/1/360220130_ftp.pd
