Abstract
Ion-pair formation in gaseous nitromethane (CH 3 NO 2 ) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO 2 − , O − , CH 3 NO 2 − , OH − , CH 2 NO 2 − and CNO − . By using nitromethane-d 3 (CD 3 NO 2 ), we found that previous mass 17 amu assignment to O − delayed fragment, is in the present experiment may be unambiguously assigned to OH − . The formation of CH 2 NO 2 − may be explained in terms of dissociative electron attachment to highly vibrationally excited molecules.
