Generalized oscillator strength for the first singlet-singlet transition in p-difluorobenzene and the cross section for energy transfer to acetone
Generalized oscillator strengths have been determined for the first singlet-singlet transition (/sup 1/B/sub 2u/reverse arrow/sup 1/A/sub g/) in p-difluorobenzene. Using this data and similar data for acetone reported earlier (K. N. Klump and E. N. Lassettre, J. Chem. Phys. 68,886(1978)) the cross section for the resonant energy transfer process C/sub 6/H/sub 4/F/sub 2/(/sup 1/B/sub 2u/)+acetone(X /sup 1/A/sub 1/) ..-->..C/sub 6/H/sub 4/F/sub 2/(/sup 1/A/sub g/)+acetone(A /sup 1/A/sub 2/) has been calculated from Huo's model (J. Chem. Phys. 66, 3572 (1977)). The calculated cross section is 85 A/sup 2/. The disagreement with the experimental value of 56 +- 2A/sup 2/ (G. L. Loper and E. K. C. Lee, J. Chem. Phys. 63, 264 (1975)) indicates that the Born approximation does not hold as well as in the case of benzene and acetone.
