Resonance-enhanced multiphoton ionization (REMPI) spectroscopy of p-chlorofluorobenzene

The S-1 <- S-0 ((A) over tilde B-1(2) <- (X) over tilde (1)A(1)) electronic transition of para-chlorofluorobenzene has been investigated using resonance-enhanced multiphoton ionization (REMPI) spectroscopy. Assignment of the vibrational structure has been achieved by comparison with corresponding spectra of related molecules, via quantum chemical calculations, and via shifts in bands between the spectra of the (CI)-C-35 and (CI)-C-37 isotopologues. In addition, we have also partially reassigned a previously-published spectrum of para-dichlorobenzene. (C) 2017 Elsevier B.V. All rights reserved.
