Abstract

The circular dichroism of (S,S)-[2,3-²H₂]oxirane has been investigated in the gas phase over the 1800-1500-Å region. While the absorption spectrum reveals only two allowed transitions, the CD spectrum shows a third transition which is magnetic dipole allowed and electric dipole forbidden. The CD sign of the first excited state complies with a quadrant rule which was formulated for the oxirane chromophore. This consignate behavior is contrary to the role of deuterium in carbonyl compounds, where an antioctant behavior is observed.
