The singlet-singlet transitions from 2 to 16 eV of 1,3,5-hexatriene have been studied by electron impact spectroscopy using 100 eV electrons and scattering angles from 0 to 28°. Transitions are observed at about 5.1, 6.2, 6.9, 8.0, 9.4 and 10.7 eV. Tentative evidence for a transition at about 4.4 eV is also given. Comparison with optical data in the 5 to 8 eV range is excellent and confirms some previously uncertain results. The angular variation of the spectral intensity indicates that all of the observed transitions in the 6 to 10 eV range gain most of their intensity from transition moments which are of higher order than electric dipole.
