โฆ Synopsis
The excitation spectra of 1.3.5-cycloheptatriene and 1,3,5.7 cycle-octatetraene have been measured with low energy electron impact spectroscopy.
The results are discussed on the basis of quantumchemical calculations.
The interaction of low energy electrons and single molecules is an important source of information about the excited states of these mol-

Electronic excitation by low energy electron impact has been \ludied for 1,3,5-trarfs-hexatriene. At = 4.2 cV. 3 weak absorption is observed. On the basis of the results of semi-empirical calculations this absorption can be assigned to the second triplet state.
