Ultraviolet resonance Raman (UVRR) spectra excited at 245 and 325 nm are reported for 1,4-benzoquinone and its 18 O 2 and d 4 isotopomers. Depolarization ratios were determined for non-resonance Raman spectra excited at 647 and 441.6 nm and solvent effects were examined for the UVRR spectra. The UVRR bands at 1665 and 1639 cm -1 , the latter of which exhibited...
