dc.description.abstractAn analysis of single vibronic level fluorescence emission spectra from the $^{1} B_{2u}$ excited state of benzene vapor by Parmenter and Schuyler has provided data on the normal modes active in the $^{1}B_{2u}\rightarrow^{1}A_{1g}$ optical transitions in benzene. It is observed that modes in only five ($a_{1g}$, $e_{2g}$, $e_{1g}$, $a_{2u}$, $e_{2u}$) of the ten vibrational symmetry groups represented in benzene have significant activity. We have such this information reexamined the assignment of the $^{1}B_{2u}\leftarrow ^{1}A_{1g}$ absorption spectrum. By assuming that vibrational activity is limited only to modes in those five groups, a refinement of previous assignments is obtained, and an extension of assignments to cover most of the principal vibrational structure is possible. More information on the intensities and on the rotational contours of specific bands is now needed to further improve the assignment of this spectrum.en_US
