Plasma desorption mass spectrometry of non‐molecular materials: Positive and negative ions formed from [Cd(SC 6 H 4 ‐2‐CH 3 ) 2 ]∞

Both positive and negative plasma desorption mass spectra of the three‐dimensionally non‐molecular material [Cd(SC 6 H 4 ‐2‐CH 3 ) 2 ]∞ contain fragment ions directly related to the lattice structure of the material. Fragment ions are observed which correspond with [CdSC 7 H 7 ] + ˙ and [CdS 2 C 7 H 7 ] − ˙ which do not involve proton transfer reactions. In contrast, a fragment ion [CdS 2 C 14 H 13 ] − ˙ would appear to involve a deprotonation reaction. The scarcity of protonated positive ion fragments may be a consequence of the sample structure and/or constraints of the analysis system.
