===Mass spectrometry of metallocenes===
[[Mass spectrometry]] of metallocene complexes has been very well studied and the effect of the metal on the fragmentation of the organic moiety has received considerable attention and the identification of metal-containing fragments is often facilitated by the [[isotope]] distribution of the metal. The three major fragments observed in mass spectrometry are the molecular ion peak, [C<sub>10</sub>H<sub>10</sub>M]<sup>+</sup>, and fragment ions, [C<sub>5</sub>H<sub>5</sub>M]<sup>+</sup> and M<sup>+</sup>.<ref name="Metallocenes"/>
