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。
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。

The decomposition of trimethylsilane and tetramethylsilane has been investigated for the first time, using hot wire (catalytic) at various temperatures. Trimethylsilane is catalytic-dissociated in these species SiH(2), CH(3)SiH, CH(3), CH(2)Si. Time of flight mass spectroscopy signal of these species are
