Abstract
Conformational preferences are determined by (de-)stabilization effects like intramolecular hydrogen bonds or steric hindrance of adjacent substituents and thus, influence the stability and reactivity of the conformers. In the present contribution, we investigate the conformational landscape of 3-methoxyphenol using a combination of high resolution electronic spectroscopy and ab initio calculations. Three of the four possible conformational isomers were characterized in their electronic ground and lowest excited singlet states on the basis of their rotational constants and other molecular parameters. The absence of one conformer in molecular beam studies can be explained by its non-planar structure in the excited state, which leads to a vanishingly small Franck-Condon factor of the respective origin excitation.
