Observation of 3-methoxyphenol rotational isomers via high resolution laser induced fluorescence spectroscopy — •Michael Schneider, Josefin Wilke, Martin Wilke, and Michael Schmitt — Institute for Physical Chemistry I, Heinrich-Heine-University, Düsseldorf

Three of four possible 3-methoxyphenol isomers have been studied via high resolution laser induced fluorescence spectroscopy. By means of evolutionary algorithms the molecular parameters of the measured spectra of different isomers were determined. With the aid of CC2/cc-pVTZ ab initio calculated structures the measured isomers were matched to one of the possible rotational isomers. The assignments agree with the results of microwave spectroscopy of other research groups. Furthermore, the transition dipole moment orientation were determined and the electronic origins of the isomers of 3-methoxyphenol and its parent molecules anisole and phenol were compared.
