Notes:
Low-Molecular Phosphorus Sulfides in the Gas PhaseIonized low-molecular phosphorus sulfides, viz. PS+, PS2+, and P2S2+· 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 P2S2+· (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.
