ion kinetic energy spectrometry [`ī´än ki¦ned·ik `en·ǝr·jē spek`träm·ǝ·trē] SPECTROSCOPY A spectrometric technique that uses a beam of ions of high kinetic energy passing through a field-free reaction chamber from which ionic products are collected and energy analyzed; it is a generalization of metastable ion studies in which both unimolecular and bimolecular reactions are considered. |
