✦ Synopsis

It is shown that the fluorescence-excitation spectrum of tetramethylethylene (2,3dimethyl-2.butene) can be vibrationally resolved in a cold beam. A partial vibrational assignment, based on the observed analogy with the absorption spectrum of ethylened,, indicates that the fluorescence is excited by a valence transition rather than a Rydberg transition as previously assumed.
