Research Abstract

The rotational isomers of several o- and m-substituted phenolos have been studied by using various electronic spectroscopies combined with the supersonic jet technique. It was found that the rotational isomers arising from the orientation of the OH group are easily identified by their electronic excitation energies. The ionization potentials of the individual rotational isomers were accurately determined by two-color ionization threshold spectroscopy. The ionization potentials of the different rotational isomers of the molecule studied show a great difference as large as 200 cm^<-1>, which suggests the possibility of separation of the rotational isomer by the ionization method. It was also found from the electronic spectra in supersonic jets that the rotational isomer selectively forms the complexes with particular solvent molecules. The large amplitude motion and intramolecular hydrogen bonding in the rotational isomer were also studied in detail.
