Low-energy (O-5 V above threshold) electron-impact excitation spectra and a trarismission spectrum are presented for acetylene. it is found that excitation via temporary negative ions plays a domimnt role. Assignments are suggested for the observed electronic excitation processes.
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.
