Electronic spectra of hydrogen-bonded 2-fluoropyridine clusters with water in a supersonic free jet

Fluorescence excitation, multiphoton ionization and dispersed fluorescence spectra of bare and hydrogen-bonded 2-fluoropyridine with water are calculated in a supersonic free jet. The appearance of low frequency vibronic bands, which are seen for bare 2-fluoropyridine, is attributed to the existence of closely lying (n,pi(super star)) state.
