Abstract
The microwave and infrared spectra of propargyl formate have been studied in the respective ranges 40–15 GHz and 4 000–50 cm–1. Evidence is presented for the coexistence of rotational isomers, one of which (probably the more stable) is shown to have a planar arrangement of heavy atoms with the alkyl group s-cis with respect to the carbonyl bond and with the acetylenic group directed away (trans) from the carbonyl group. The dipole moment was measured in dilute benzene solution at 297 K to be 1.94 ± 0.02 D.Keywords
