Abstract
The Raman spectra of solution grown Potassium thiourea chloride (KTC) crystals were studied in the temperature range of 125Â K to 400Â K and in the wave length region of 100 to 4000Â cmâ1. The vibrational frequencies of the thiourea metal complex were identified and assigned. The temperature dependence Raman spectra shows discontinuities, which we infer is due to modifications of bonds associated to CS. Based on the evolution of thermosensitive bands the transitions were identified around 250Â K. The modifications observed in the vibration spectra of KTC shows strong interaction of the metal complex with sulfur atom of thiourea. The second harmonic generation was confirmed by Kurtz Perry powder technique and the efficiency was found to be 1.5 times as that of the KDP sample used as reference.
