Isotope clusters in library electron ionization mass spectra of germanes often appear a few u lower than theoretically expected from elemental composition; for example, the dominant peak of the Ge(4)H(10)(+) pattern is shifted 8 u down. This phenomenon is due to combinations of three essential components: the molecular ion Ge(n)H(2n+2)(+) and two products of hydrogen elimination, Ge(n)H(+) and Ge (n)(+) . Using these components, isotope clusters can be accurately projected for germanium hydrides from Ge(2)H(6) up to Ge(5)H(12).
在锗的库仑电离质谱的同位素簇中，经常会出现比从元素组成理论上预期的低几个 u 的情况；例如，Ge(4)H(10)(+) 模式的主要峰向下移动了 8 u。这种现象是由三个基本成分的组合引起的：分子离子 Ge(n)H(2n+2)(+) 和两个氢消除产物 Ge(n)H(+) 和 Ge (n)(+)。利用这些成分，可以准确地预测从 Ge(2)H(6)到 Ge(5)H(12)的锗氢化物的同位素簇。
