S-(-)-1-phenyl ethyl ammonium(1+) sulphate and S-(-)-1-phenyl ethyl ammonium(1+) hydrogen phosphate 2.5 hydrate, preparation and characterization of crystallographic, optical and dielectric properties

Abstract

S-(-)-1-phenyl ethyl ammonium(1+) sulphate and S-(-)-1-phenyl ethyl ammonium(1+) hydrogen phosphate 2.5 hydrate were prepared and the obtained substances crystallized in non-centrosymmetric space groups. Dielectric properties and second harmonic generation were studied.

Both substances were further characterized by chemical analysis, X-ray structural and powder analysis, infrared and Raman spectroscopy and thermal analysis (DTA, TGA).
