The radiative lifetimes and the electronic quenching rate constants of the PF(A(3)II(0,1,2)) and PF(d(1)II) states have been measured for 300 K conditions using the laser-induced fluorescence technique. The excited states were generated by pulsed laser excitation from the PF(X(3) Sigma(-)) and PF(a(1) Delta) molecules, which were produced by passing PF3 through a microwave discharge in a flow reactor. The radiative lifetime of PF(A,v’=0) for a 300 K Boltzmann distribution of rotational and spin-orbit states is 4.2 +/- 0.2 mu s; the lifetime for PF(A,v’=1) was similar to 25% shorter than for PF(A,v’=0). The lifetime of PF(d(1)II,v’=0) is 0.96 +/- 0.05 mu s. The electronic quenching rate constants of PF(A and d) by 24 diatomic and polyatomic molecules plus He and Ar were measured. Both states have large quenching constants for most molecules; however, the quenching constants for He, Ar, CF4, SiF4, and SF6 are very small. The relaxation among the spin-orbit states of PF(A(3)II(0,1,2)) in He and Ar was studied by observing the wavelength resolved emission spectra from the Omega = 0, 1 and 2 levels. A propensity for direct transfer of population from PF(A(3)II(2)) to PF(A(3)II(0)), rather than through the PF(A(3)II(1)) level, was observed for He collisions; this propensity was reduced for collisions with Ar. The vibrational relaxation constants of PF(A,v’=1) and PF(d,v’=1) also were measured. The spin-orbit relaxation rates are more rapid than the vibrational relaxation rates for PF(A(3)II(0,1,2)). The laser-induced PF(A(3)II, v’=0,1 --> X(3) Sigma(-),v ") and PF(d(1)II,v’=0,1,2 --> a(1) Delta,v "; b(1) Sigma(+),v ") emission spectra were recorded to obtain relative band intensities.
