✦ Synopsis
A harmonic two-photon cross section sum rule for benzene bZu modes (vld and vIs) in the .& 'BZU+-% 'A,, transition is derived.
An approximate (but accurate) form of this rule based on skeletal mode displacements is used to obtain absorptivity values for C6H6 14y (6.3X 1O-5o cm4 s mol-' photon-') and IS? (1.6X 1O-5o cm4 s mol-' photon-') from the measured absorptivity ratio, 4, (15 )/a,, ( ) and from the measured value of 146. We also report the sum-rule-predicted hot and cold band absolute absorptivities in the other Ddb benzenea, C6D6, 13C.sH6 and 13C6Da.
