Abstract

Sulphamic acid (SA) and L-methionine added sulphamic acid crystals (LMSA) were grown by slow evaporation technique at room temperature. The Single crystal XRD studies revealed that the grown crystals possessed orthorhombic crystal structure. The presence of various functional modes was confirmed by RAMAN analysis. The EDAX analysis confirmed the presence of L-methionine in the grown LMSA crystal. The surface morphology of crystals was studied. The larger size crystals revealed the excellent crystallinity. The stability of the crystals was ascertained from thermo gravimetric and differential thermal analysis. The third order nonlinear refractive index, nonlinear absorption coefficient and third order optical susceptibility were calculated by the Z-scan technique.
