Nonlinear optical activity and spectroscopy of L-nitrohistidine monohydrate

Abstract

Comparative investigation of vibrational (IR and Raman) and NMR spectra of L-nitrohistidine monohydrate (L-NH·H2O) and L-histidine (L-His) has been performed with allowance for structural data. Nonlinear-optical activity and the range of transparency of L-NH·H2O are determined. Influence of nitrogroup on structural, spectral, and nonlinear-optical properties is emphasized.
