摘要：

A harmonic two-photon cross section sum rule for benzene b2u modes (ν14 and ν15) in the Ã1B2u←X̃1A1g transition is derived. An approximate (but accurate) form of this rule based on skeletal mode displacements is used to obtain absorptivity values for C6H6 1410 (6.3×10-50 cm4 s mol-1 photon-1) and 1510 (1.6×10-50 cm4 s mol-1 photon-1) from the measured absorptivity ratio, δ↑↑(15)/δ↑↑(14) and from the measured value of 1401. We also report the sum-rule-predicted hot and cold band absolute absorptivities in the other D6h benzenes, C6D6, 13C6H6 and 13C6D6. © 1990.
