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.

摘要

通过使用向列型主体中取向胶体悬浮液的线性偏振红外光谱以及质谱法，对四肽甘氨酰 -（L）- 脯氨酰 - 甘氨酰 - 甘氨酸及其氢醌酸盐进行了红外光谱和结构解析。进行了量子化学从头计算，以评估所研究化合物的电子结构和光学性质。
