Abstract

Dipeptide (L)-threonyl-(L)-methionine (Thr-Met) is characterized structurally by means of a solid-state linear polarized IR- spectroscopy (IR-LD) of oriented samples as a colloidal suspension in nematic liquid crystal and quantum chemical ab initio calculations. Vibrational analysis supports the experimental data as well. The role of intermolecular hydrogen bonding on conformational behavior and spectroscopic properties of the compound, studied in solid state is determined.
