Spectral, thermal and optical properties of adenosinium picrate: a nonlinear optical single crystal.

A new organic nonlinear optical material adenosinium picrate (C10H14N5O4+, C6 H2 N3 O7-) was synthesized. The single crystal X-ray diffraction revealed the non-centrosymmetric crystal structure, which is an essential criterion for second harmonic generation. The crystalline nature of the grown crystals was confirmed using powder XRD techniques.

Spectral, thermal and optical properties of L-tryptophanium picrate: a nonlinear optical single crystal.

A new organic nonlinear optical material L-tryptophanium picrate was synthesized. From the powder XRD pattern the various planes of reflections were identified. The grown crystals were subjected to FT-IR and (1)H NMR spectral analyses to confirm the synthesized compound.
