General description
四甲基硅烷已被国际纯粹与应用化学联合会（IUPAC）推荐为所有核素的通用参考品。它通常用作核磁共振（NMR）的参考标准品，用于测量质子的化学位移，TMS在氯仿、甲醇和二甲基亚砜等溶剂中的1H化学位移的温度依赖性已进行了研究。
Application
四甲基硅烷可用作定量NMR（qNMR）法定量分析药用植物提取物和草药产品的内标物。它也可用作FT-IR光谱法和质子核磁共振（1H NMR）技术研究过氧化物化学系统中等规聚丙烯交联反应的内标物。

The open-chain tetrapyrrole compound bilirubin was investigated in chloroform and dimethyl sulfoxide solutions by liquid-state NMR and as solid by (1)H, (13)C, and (15)N magic-angle spinning (MAS) solid-state NMR spectroscopy. Density functional theory (DFT) calculations were performed to interpret the
