A technique is described for the measurement of electron attachment to short-lived ({approx lt}10{sup {minus}9} s) excited species. Preliminary results are presented for photoenhanced electron attachment to short-lived electronically-excited states of triethylamine molecules produced by laser two-photon excitation. The attachment cross sections for these excited states are estimated to be >10{sup {minus}11} cm{sup 2} and are {approximately}10{sup 7} larger compared to those for the unexcited (ground-state) molecules. 8 refs., 4 figs.
