The equilibrium geometries, excitation energies, force constants, and vibrational frequencies of the low‐lying electronic states X 2 B 1 , 2 A 1 , 2 B 2 , and 2 A 2 of the PF 2 radical have been calculated at the MRSDCI level with a double zeta plus polarization basis set. Our calculated geometry, force constants, and vibrational frequencies for the X 2 B 1 state are in good agreement with experimental data. The electronic transition moments, oscillator strengths for the 2 A 1 → X 2 B 1 and 2 A 2 → X 2 B 1 transitions, and radiative lifetimes for the 2 A 1 and 2 A 2 states are calculated based on the MRSDCI wave functions. © 1994 by John Wiley & Sons, Inc.
