  • Low‐Molecular Phosphorus Sulfides in the Gas PhaseIonized low‐molecular phosphorus sulfides, viz. PS+, PS, and P2S are generated by electron‐impact (EI) fragmentation of P4S10. The results of collisional‐activation (CA) mass spectra and semiempirical MO calculations suggest a linear structure for SPS+ (D∞;h) and a ring structure for P2S (D2h). As shown by neutralization‐reionization mass spectrometry (NRMS) all the ions mentioned above can be reduced to the corresponding neutral molecules. Thus, low‐coordinated phosphorus sulfides containing multiple‐bond systems prove to be stable molecules in the dilute gas phase.
