The semiorganic non-linear optical crystal bisthiourea magnesium sulphate (BTMS) was grown by slow evaporation technique using water as solvent. Vibrational spectra were recorded to determine the symmetries of molecular vibrations. The observed Raman and infrared bands were also assigned and discussed. The optical transmission spectral study was carried out to test the transmitting ability of the crystal in the visible range. The second harmonic generation test of BTMS revealed the non-linear nature of the crystal. The TGA/DTA curve was also recorded for the experimental crystal.
采用水作为溶剂，通过缓慢蒸发技术生长出半有机非线性光学晶体双硫脲硫酸镁（BTMS）。记录振动光谱以确定分子振动的对称性。还对观察到的拉曼光谱和红外光谱带进行了归属和讨论。进行了光学透射光谱研究，以测试该晶体在可见光范围内的透光能力。BTMS的二次谐波产生测试揭示了该晶体的非线性特性。还记录了实验晶体的热重/差热曲线。
