| Abstract: | Nonlinear optical (NLO) crystals are vital for applications in photonics and optoelectronics. Thiourea, an organic NLO material, is particularly attractive due to its optical nonlinearity, stability, and hydrogen bonding network. In this study, single crystals of thiourea were investigated using Fourier Transform Infrared (FTIR) spectroscopy and Differential Scanning Calorimetric (DSC). FTIR spectra confirmed the characteristic vibrational modes of functional groups, validating molecular integrity and crystal quality. DSC analysis was employed to evaluate the thermal response and calculate key thermodynamic parameters, including enthalpy (ΔH), entropy (ΔS), and Gibbs free energy (ΔG). The results indicate strong intermolecular interactions and favorable thermal stability, making thiourea suitable for nonlinear optical device applications. This combined spectroscopic and calorimetric approach provides insight into the structure–property relationship of thiourea crystals and establishes their potential in advanced photonic applications. |
