Rate constants and product branching ratios for POxCl y-ions reacting with H and H2 were measured in a selected ion flow tube (SIFT) from 298 to 500 K. PO2Cl-, PO2Cl2-, POCl2-, and POCl3- were all unreactive with H2, having a rate constant with an upper limit of -12 cm 3 s-1. PC2Cl2- did not react with H atoms either, having a similar rate constant limit of -12 cm3 s-1. The rate constants for PO 2Cl-, POCl2-, and POCl 3- reacting with H showed no temperature dependence over the limited range of 298-500 K and were approximately 10-20% of the collision rate constant Cl abstraction by H to form HCl was the predominant product channel for PO2Cl-, POCl2-, and POCl3-, with a small amount of Cl- observed from POCl2- + H. Reactions of O2 and O 3 with the POCl- products ions from the reaction of POCl2- + H were observed to yield predominantly PO 3- and PO2-, respectively. POCl - reacted with C2 and O3 with rate constants of 8.9 ± 1.1 × 10-11 and 5.2 ± 3.3 × 10 -10 cm3 s-1, respectively. No associative electron detachment in the reactions with H atoms was observed with any of the reactant ions; however, detachment was observed with a PO- secondary product ion at high H atom concentrations. Results of new G3 theoretical calculations of optimized geometries and energies for the products observed are discussed.

The products of the reaction of laser-ablated red phosphorus and dioxygen have been studied using experiment and theory. The bands at 480.3 and 1273.3 cm-1, previously attributed to PO3 in the matrix isolation IR experiments, are reassigned to PO3- Also observed in experiment are PO2, PO2-, P2O, OPOPO, P4, and higher oxides.
