Abstrakt: Rotationally resolved spectra of the A ̃ 2 A ′ ′ – X ̃ 2 A ′ ′ origin bands for both trans- and cis-conformers of 1-vinylpropargyl radical (1VPR) are experimentally studied. Rotational constants for both ground and electronically excited states are experimentally determined. The stability of the A ̃ 2 A ′ ′ excited state of the cis-1VPR is found to be higher than that of trans-1VPR, which is likely due to additional π-overlap and increased pπ electron delocalization in the excited state of cis-1VPR.
