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 dc.format.extent 85857 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ON THE $^{1} B_{2u}-^{1} A_{1g}$ ABSORPTION SPECTRUM OF BENZENE en_US dc.type article en_US
