Abstract 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$_{4}$H10+ pattern is shifted 8 u down. This phenomenon is due to combinations of three essential components: the molecular ion Ge$_{n}$H2n+2+ and two products of hydrogen elimination, Ge$_{n}$H$^{+}$ and Gen+. Using these components, isotope clusters can be accurately projected for germanium hydrides from Ge$_{2}$H$_{6}$ up to Ge$_{5}$H$_{12}$.
