Solvent complexes of jet-cooled β-phenylethylamine.
Laser-induced fluorescence spectroscopy was used to investigate β-phenylethylamine molecules that were cooled via supersonic gas expansions. The bare molecule spectra reveal 0-0 transitions that can be attributed to four separate conformers. Upon the addition of water or alcohol solvents, a series of new peaks is induced that appear to be built off separate bare molecule transitions. This is a pattern that is markedly different from the one seen for solvent addition to tyramine, which includes an-OH in the para position. As a result, definite hypotheses can be made to explain the influence of the para-OH in affecting solvent induced conformations.
