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

The significant intensity in overtones of the benzene ring C-C stretch ν9 (1578 cm−1) and the carbonyl CO stretch ν8 (1671 cm−1) modes and their combination bands with other five vibrational modes indicates the extensive structural deformation of the carbonyl moiety and the phenyl ring in the excited state with respect to the ground state.
