(Tin-119,锡-117)耦合卫星是可见的CP/MAR光谱的四(三甲基锡基)甲烷和一系列的四锡环己烷,在固体和溶液状态下的值是相等的实验误差。来自前一化合物的单个信号具有仅28 Hz的线宽。对于1,4-双(三甲基甲锡烷基)苯获得的宽谱线(Δν1/2 320 Hz)排除了5 J(SnSn)的观察。
(Tin‐119, tin‐117) coupling satellites are visible in the CP/MAR spectra of tetrakis(trimethylstannyl)methane and of a series of tetrastannacyclohexanes, the values in the solid and solution states being equal within experimental error. The single signal from the former compound has a line width of only 28 Hz. The broad lines (Δν1/2 320 Hz) obtained for 1,4‐bis(trimethylstannyl)benzene precluded the observation of 5J(SnSn).
