  Rate constants for electron attachment to PCl3 and POCl3 have been measured over the temperature range 296–552 K in 135 Pa of helium gas, using a flowing-afterglow Langmuir-probe apparatus. Electron attachment to PCl3 is dissociative, producing only Cl− ions in this temperature range. The rate constant is 6.4±1.6×10−8 cm3 s−1 at 296 K and increases with temperature in a way that may be described by an activation energy of 43±10 meV. Electron attachment to POCl3 is a richer process in which a nondissociative channel (POCl3−) competes with two dissociative ones (POCl2− and Cl−). The rate constant for electron attachment to POCl3 is 1.8±0.4×10−7 cm3 s−1 at 296 K and is relatively temperature independent in our temperature range. POCl2− is the major product over the entire temperature range. Ab initio MP2 and MP4 calculations have been carried out on ground-state neutral and anionic PCln and POCln for n=1–3. The calculated adiabatic electron affinities agree with experimental estimates where available. The calculations yield C3v structural symmetries for PCl3 and POCl3, and Cs symmetries for PCl3− and POCl3−. The degree of distortion between the respective neutrals and anions is explored in the calculations, and the implications for electron attachment reactions are outlined.

  Time resolved spectroscopy of the atomic fine structure transition of Cl, 2P1/2–2P3/2 at 882.35 cm−1 is applied to derive relative yields of the metastable level 2P1/2 of Cl(Cl*) from the photodissociation by excimer laser radiation of KrF or ArF. Molecules such as HCl, CH3Cl, CH2Cl2, phenyl chloride, and PCl3 are studied, getting for the first time the possibility of systematic comparison of yields for Cl* and also of earlier results on heavier halogens obtained by other authors using different methods. Most yields determined in the present work are close to a value as calculated from the statistical weights of the two fine structure levels of Cl. This finding is related in a simple diabatic picture to the small spin–orbit interaction in Cl compared to that in iodine. Additionally some rate constants for the collisional quenching of the metastable Cl by the parent molecule are derived.

  The reaction of metastable Ar(P-3(0,2)) atoms with PCl3 has been developed as a source of metastable PCl(b(1) Sigma(+)) molecules in a flow reactor at 300 K. The total quenching rate constants were measured for 23 molecules, and they are in the 2 x 10(-14) to 3 x 10(-11) cm(3) molecule(-1) s(-1) range. An electronic-to-vibrational (E-V) energy-transfer mechanism is used to discuss the quenching of PCl(b(1) Sigma(+)), and the experimental rate constants are compared to similar data for PF(b(1) Sigma(+)), NCl(b(1) Sigma(+)), and NCl(b(1) Sigma(+)) molecules. An influence of the type of halogen substituent in the reagent molecule on the quenching rate constants is identified, and a role for attractive molecular interactions needs to be added to the E-V model. The Ar(P-3(0.2)) + PCl3 reaction gives vibrationally excited PCl(b(1) Sigma(+)) molecules and the Delta nu=+1 and +2 sequences were observed in addition to the Delta nu=0 main sequence.
