Abstract

Vibrational transitions of jet-cooled phenol have been detected by nonresonant two-photon ionization due to a UV laser from 3400 to 14000 cm(-1). The UV frequency dependence of the IR-UV double resonance signals is used for discussion on the mechanism of ionization. The spectrumshows a well-resolved structure due to the first to the fourth quantum of OH stretching vibrations, CH overtones and various combination vibrations. The vibrational frequency, anharmonicity and the dissociation energy of the OH stretching mode has been measured. The bandwidth ofthe OH overtone is found to decrease with increase in the vibrationalquantum number. (C) 1998 Elsevier Science B.V.
