Using a crossed electron-ion beams method, we measured absolute cross sections for electron-impact dissociation of the CD{sub 3}{sup +} molecular ions producing CD{sub 2}{sup +} fragment ions and CH{sub 3}{sup +} ions yielding CH{sup +} and C{sup +} fragment ions over a collision energy range from a few eV up to 100 eV. The total experimental uncertainties are about 12% at the maximum of the curves of cross sections (peak of the cross section for the CH{sup +} channel). The obtained results suggest important roles played by predissociation of bound states in the production of both the CH{sup +} and C{sup +} fragment ions. Good agreement is found with other results reported for the CH{sup +} fragment, but some differences are found for the CD{sub 2}{sup +} and C{sup +} fragments.
