An Ar‐Kr ion laser was used to excite the Raman spectrum of powdered anthracene with two laser lines of 4880 and 6471 Å. There are significant differences in the intensity distribution in these two Raman spectra. These differences can be best explained by considering that Raman intensities are contributed by two allowed excited states of anthracene, and their contributions depend upon the laser frequency. From these Raman spectra, it is also possible to infer the vibrational structures in the higher energy, structureless excited state of anthracene.
