Abstract
Low-frequency intermolecular vibrations in S0 and S1 states of p-fluorophenol (pFP) methanol binary complex have been studied using laser induced fluorescence (LIF) spectroscopy in a supersonic jet expansion. Vibrational fundamentals of five such modes show up in fluorescence excitation (FE) spectrum, and corresponding ground state frequencies are obtained measuring disperse fluorescence (DF) spectra. Signatures of strong coupling between the hydrogen bond stretching fundamental (σ01) and a ring mode of pFP moiety in S1 state are revealed. In comparison with the analogous pFP-water complex, the present system displays very low threshold (∼170 cm−1) for vibrational energy relaxation in S1 state.
