  • Title: Aromatic dipeptides and their salts--solid-state linear-dichroic infrared (IR-LD) spectral analysis and ab initio calculations.
    Author: Ivanova BB.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2008 Jul; 70(2):324-31. PubMed ID: 18029224.
    Abstract:
    Stereo-structural analysis and IR-bands assignment of the aromatic dipeptides L-tryrosyl-L-phenylalanine (Tyr-Phe), L-phenylalanyl-L-tyrosine (Phe-Tyr) and their hydrochloride salts have been carried out by means of IR-LD spectroscopy of oriented as nematic liquid crystal suspension solid samples. The experimental data are compared with known crystallographic ones and theoretical predicted geometries at RHF/ and UHF/6-31G**.
