摘要
The Raman spectra of 9,10-anthraquinone (AQ) and 9,10-anthraquinone-d8 are examined. Raman band assignments are made from this data and from a published normal coordinate analysis. The Raman spectra of AQ at 5 K is reported and vibrational assignments for the phosphorescence spectra of AQ in n-hexane at 4.2 K are reexamined in light of new 3B1g → 1Ag phosphorescence data. Contrary to previous work from this laboratory, it is concluded that although higher order vibronic interactions may be operative between the two closely spaced 3Au-3B1g electronic states, these interactions are not manifested in the phosphorescence spectra of AQ in n-hexane at 4.2 K. © 1979 American Chemical Society.
