The effect of nitric acid (HNO(3)) addition on the growth of triglycine sulphate (TGS) crystal has been studied from the aqueous solution for various concentrations of nitric acid. Significant changes in the crystal size and morphology have been observed in all the grown samples. Single crystal and powder X-ray diffraction analyses confirm the structure and cell parameter values of pure and HNO(3) doped TGS crystals. FT-Raman and FTIR spectra confirm the characteristics absorption bands of pure and HNO(3) doped TGS crystals. The composition of TGS crystals have been confirmed by CHNS analysis. Physical properties such as thermal, dielectric and mechanical studies have been performed for the pure and HNO(3) doped TGS crystals. The dielectric constants of the crystals have been studied as a function of frequency. The results suggest that the HNO(3) is doped into TGS crystal and that the doping increases its dielectric constant.
研究了不同浓度硝酸溶液中添加硝酸对三甘氨酸硫酸盐（TGS）晶体生长的影响。在所有生长的样品中都观察到晶体尺寸和形态的显著变化。单晶和粉末 X 射线衍射分析证实了纯 TGS 和 HNO3 掺杂 TGS 晶体的结构和晶胞参数值。FT-Raman 和 FTIR 光谱证实了纯 TGS 和 HNO3 掺杂 TGS 晶体的特征吸收带。通过 CHNS 分析确认了 TGS 晶体的组成。对纯 TGS 和 HNO3 掺杂 TGS 晶体进行了热学、介电和力学等物理性质的研究。研究了晶体的介电常数随频率的变化。结果表明，HNO3 掺杂到 TGS 晶体中，掺杂提高了晶体的介电常数。
