Abstract
The absorption and circular dichroism spectra of trans‐cyclooctene, α‐pinene and β‐pinene were measured in the gas phase in the vacuum ultraviolet. The absorptions were recorded to 110 nm and the CD spectra to 150 nm. Consistent assignments were made for these three ethylene chromophore molecules using the measured anisotropy factors (g = Δε/ε) to characterize transitions. Also, available theoretical work was used as a guide. In particular, magnetic dipole allowed transitions in the parent molecule, ethylene, have been characterized and assigned.Keywords
