| Abstract: | Time-resolved detection, which is not possible with conventional GC, MS, or GC-MS, is of particular importance in monitoring the products of catalytic reactions. Resonance-enhanced multiphoton ionization (REMPI) can ionize target molecules with high selectivity and sensitivity, and has been widely applied to the study of structure and energy-transfer dynamics of atoms, molecules and free radicals1,2]. |
