Notes:
Vibrational progressions in the A′→X(v″) fluorescence of ClF in Ar and Kr matrices with 1〈v″〈9 are observed in the spectral range from 600 to 900 nm with lifetimes of 141 ms. Two-photon excitation leads to emission from the ionic D′ state to the A′, 2 3Π2, and 2 3Δ2 valence states in the range from 390 to 470 nm with 50 ns lifetime. Ground state parameters ωe and ωexe as well as Te values for the A′ and D′ states are derived. Matrix and Stokes shifts are observed and the large linewidth of the D′ emission is related to the strong coupling of the ionic state to the lattice. Dissociation quantum efficiencies of 5% and 4.8% are determined for kinetic energies of the F fragment of 0.92 eV and 0.39 eV in Ar (19 K), respectively. © 2001 American Institute of Physics.
