Radiative Lifetime and Quenching Rate Constants of PF(b(1) Sigma+) and Tests for an Electronic to Vibrational Energy Transfer Quenching Mechanism.
Abstract
Methods were developed to generate and isolate the PF(X(3)sigma, a(1)delta, b(1)sigma+, A(3)pi and d(1)pi) states in a flow reactor. Radiative lifetimes and total removal constants at 300 K have been measured. Except for halogens, the PF(b(1)sigma+) state is stable to chemical reaction. The other PF states seem to participate in chemical reactions at 300 K. Preliminary experiments were done with PCl(b(1)sigma+) and NCl(b(1)sigma+) to establish their radiative lifetimes. The reactions of excess H atoms with PF2Cl and PF2Br was explored as a chemical source for the generation of PF(a(1)delta) from the H + PF2 secondary reaction. (jg)
