Naphthalene excited state geometry

In complex organic molecules calculations of the geometry of excited states and hence predictions of chemiluminescent reactions are very difficult however, as is well known, in polycyclic aromatic hydrocarbons there are relatively small differences in the configurations of the ground state and the excited state. Moreover, the chemiluminescence produced by the reaction of aromatic hydrocarbon radical anions and radical cations is due to simple one-electron transfer reactions, especially in cases where both radical ions are derived from the same aromatic hydrocarbon, as in the reaction between 9.10-diphenyl anthracene radical cation and anion. More complex are radical ion chemiluminescence reactions involving radical ions of different parent compounds, such as the couple naphthalene radical anion/Wurster s blue (see Section VIII. B.). [Pg.69]

The predicted geometry for the first excited state of naphthalene has been calculated by Fujimura, Yamaguchi, and Nakajima (35) see Table IV. The calculations do not take into account the possible nonplanarity of the excited state molecule nor are electron-electron repulsions expected to be the same for the first excited state and the dianion. However similarities in the trends of the bond lengths found for naphthalene (TMEDLi)2naphthalene and calculated for the B2u( excited state of neutral naphthalenes are encouraging (Table IV). [Pg.74]
