Structural and spectroscopic elucidation of tetrapetide glycyl-(L)-prolyl-glycyl-glycine and its hydrogensquarate.


PMID 18782067

Abstract

The IR-spectroscopic and structural elucidation of tetrapeptide glycyl-(L)-prolyl-glycyl-glycine and its hydrogensquarate was performed by employing linear-polarized IR-spectroscopy of oriented colloid suspensions in nematic host as well as mass spectrometry. Quantum-chemical ab initio calculations were carried out in order to evaluate both the electronic structure and optical properties of the compound studied.
