Growth and spectroscopic analysis of semi-organic bisthiourea sodium fluoride crystal

A semi-organic bisthiourea sodium fluoride (BTSF) is synthesized at ambient temperature and the single crystal of bisthiourea sodium fluoride is grown in slow evaporation technique using water as solvent. The cell parameters of the grown crystal are estimated from single crystal XRD analysis and also unambiguous assignments of fundamental modes of various molecular groups are made from the recorded FTIR and FT-Raman spectra. The thermal stability of the grown crystal is investigated using thermo-gravimetric analysis studies. Optical transmittance percentage of the grown crystal is measured from UV-VIS studies.
