Detection of PO, Cl, and P from the Photodissociation of POCl3 at 193nm

摘要

The photodissociation of POCl3 has been investigated using the unfocussedradiation of an excimer operating at 193 nm. PO, P and Cl radicals were probed by resonance-enhanced multiphoton ionization (REMPI), and signal intensities were studied as a function of excimer laser power. The probe laser was found to produce a non-resonant PO(+) background signal in addition to the resonant ionization signal of neutral PO. A set of possible dissociation pathways has been postulated.
