Resonance Raman spectroscopy and density functional theory study of the photodissociation dynamics of acetophenone in cyclohexane solution

Abstract: Resonance Raman spectra were acquired for acetophenone using 228.7, 239.5, and 245.9nm excitations in cyclohexane solution. The spectra display overtones of the benzene ring C–C stretch (1578cm−1) and the carbonyl C (1671cm−1) modes and their combination bands with other five vibrational modes. A preliminary resonance Raman intensity analysis was done and these results for acetophenone were compared to the those previously reported for 2-hydroxyacetophenone. The differences between the vibrational reorganizational energies for acetophenone relative to those of 2-hydroxyacetophenone were briefly discussed. [Copyright &y& Elsevier]
