A comprehensive experimental and computational study of highly efficient organic NLO crystal: Anilinium -L-Tartrate

Abstract In the field of nonlinear optics, the organic materials have new corners compared to inorganic materials. Aniline as well as tartrate possesses high nonlinear optical behaviour especially for second harmonic generation. Single crystals of Anilinium-L-Tartrate (ALT) salt is grown from solution growth technique. ALT crystal belongs to triclinic system with space group P1 which is basically a donor acceptor organic material. The grown crystal is subjected to characterisations such as optical, mechanical and spectral studies to propose the material for useful applications. The details of theoretical calculations of macroscopic nonlinear properties molecular orbital calculations and Hirschfield Analysis are also reported in the present work.
