Article abstract of DOI:10.1021/j100023a003

Jet-cooled fluorescence excitation spectra and selected single vibronic level dispersed fluorescence spectra are presented for p-methoxy-trans-stilbene and p-methoxy-p'-methyl-trans-stilbene.Two stable conformers of the methoxy group are evident in the sp
