## Abstract Using Wilson's GFβmatrix method as modified by Higgs for infinite helical polymers, dispersion curves and the frequency distribution function have been calculated for polyβLβproline II chain. Infrared spectrum is obtained and a UreyβBradley force field, which provides best fit with the
The synthetic polymer poly-L-proline exists in two conformational forms, I and 11, the structures of which have been elucidated by x-ray crystallography.'-3 Form I is a right-handed helix with all peptide bonds in the cis configuration, and is stable in pyridine and aliphatic alcohols. Form I1 is a
A correlation between the energies of electronic singlet transitions in benzodiazepines and their biological activity, which was revealed earlier by means of negative ion mass spectrometry with resonance electron capture, has been verified with a UV absorption spectroscopy investigation. Also, it ha
