Popis:	We recorded the IR spectra of C 2 H 4 + trapped in solid Ar through electron bombardment of a mixture of ethylene and Ar during matrix deposition. The four most intense lines of C 2 H 4 + were observed and assigned according to comparison with the literature data for ethylene with solid Ne and the predicted vibrational anharmonic wavenumbers. Experiments involving further UV irradiations of the matrix samples were performed in the region 345–225 nm. Upon UV radiation, lines of C 2 H 4 + decreased and lines corresponding to C 2 H 4 , C 2 H 2 , and C 2 H 3 increased, indicating that the photodissociation and photo-assisted neutralization of C 2 H 4 + in the matrix may occur simultaneously.
