  • Title: Electronic absorption and vibrational spectra and nonlinear optical properties of L-valinium succinate.
    Author: Jesintha John C, Xavier TS, Lukose G, Hubert Joe I.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2012 Jan; 85(1):66-73. PubMed ID: 22020163.
    Abstract:
    FT-Raman and FTIR techniques have been applied to investigate the potential nonlinear optical material l-valinium succinate. A detailed interpretation of the vibrational spectra was carried out with the aid of potential energy distribution analysis. Density functional theory is applied to explore the nonlinear optical properties of the molecule. Good consistency is found between the calculated results and the experimental data for IR and Raman spectra. The natural bond orbital analysis confirms the occurrence of strong intramolecular N-H⋯O hydrogen bonding.
