The electronic spectra of three conjugated cis-dienyl systems, 1,3-cyclopentadiene, 1,3-cyclohexadiene, and 1,3-cycloheptadiene have been investigated using electron-impact spectroscopy. Spectra were obtained at impact energies ranging from 20 to 75 eV and scattering angles from 5/sup 0/ to 80/sup 0/. A single singlet ..-->.. triplet transition was observed for each molecule at 3.10, 2.94, and 2.99 eV, respectively. Information on the Franck--Condon envelopes was obtained for these transitions. The N..-->..V/sub 1/, N..-->..V/sub 2/, and V/sub 3/, and several Rydberg transitions were also observed in each substance. Some previous unreported superexcited states lying above the first ionization potential were detected.
