title: Solvent effects on the coexistence of localized and delocalized 4,4'-dinitrotolane radical anion by resonance Raman spectroscopy.
abstract: The resonance Raman spectrum of the simple alkyne bridge in 4,4'-dinitrotolane radical anion shows two distinct bands, providing proof of the solvent-dependent coexistence of charge-localized and -delocalized species. The Raman spectra of normal modes primarily involving the charge-bearing -PhNO(2) units also support the coexistence of two solvent-dependent electronic species. The temperature dependence of the spectra of the bridging unit shows an inverse relationship between the solvent reorganization energy (lambda(s)) and the temperature.
