Abstract:
Large single crystals of the tetragonal (space group I 4̅2 d ) guanidinium zinc sulfate, [C(NH 2 ) 3 ] 2 Zn(SO 4 ) 2 , were grown and the crystal structure was redetermined. Vibrational spectra obtained by Raman and IR investigations are presented, together with an assignment of the observed vibration modes. Precise refractive index data in the wavelength range from 0.365 to 1.083 μm are given. [C(NH 2 ) 3 ] 2 Zn(SO 4 ) 2 is introduced as a new stimulated Raman scattering (SRS)-active crystal with three SRS-active vibration modes with ω SRS1 ≈ 985 cm –1 , ω SRS2 ≈ 3390 cm –1 and ω SRS3 ≈ 1015 cm –1 . They allow for the generation of broadband nonlinear emission via χ (3) - (SRS and Raman-induced four wave mixing, RFWM) as well as cascaded χ (2) ↔ χ (3) - processes.
