Time-resolved resonance Raman studies on proton-induced electron-transfer reaction from triplet excited state of 2-methoxynaphthalene to decafluorobenzophenone.

In this paper, time-resolved resonance Raman (TR3) spectra of intermediates generated by proton-induced electron-transfer reaction between triplet 2-methoxynaphthalene ((3)ROMe) and decafluorobenzophenone (DFBP) are presented. The TR3 vibrational spectra and structure of 2-methoxynaphthalene cation radical (ROMe(•+)) have been analyzed by density functional theory (DFT) calculation. It is observed that the structure of naphthalene ring of ROMe(•+) deviates from the structure of cation radical of naphthalene.
