Crystal Structure and Third Order Nonlinear Optical Studies on 2-phenylbenzimidazolium-p-toulenesulphonate.

A new third order nonlinear optical single crystal of 2-phenylbenzimidazolium-ptoulenesulphonate (PBITS) was grown by the solvent evaporation technique using methanol as a solvent. The single crystal XRD analysis reveals that crystals belong to the triclinic system. An NMR and FTIR study confirms the formation and vibrational analysis present in the compound. UV-Vis absorption studies were also carried out for the crystal. Nonlinear refractive index (n2), absorption coefficient (ß) and third order nonlinear optical susceptibility ((X(3))) of the crystals were evaluated by Z-Scan studies. [ABSTRACT FROM AUTHOR]
