- Abstract
The field-assisted dissociative ionization of CH2I<STACK>+2</STACK> irradiated by a 60-fs 800-nm laser with different laser intensities (1–4 × 1014 W/cm2) is studied both experimentally and theoretically. The different fragmentation patterns are observed in the experiment with a time-of-flight mass spectrometer. In the theoretical aspect, the Gaussian 03 program is applied to calculate the potential energies of CH2I<STACK>+2</STACK> as functions of the C&bond;I and C&bond;H bond distances and I&bond;C&bond;I bond angle under external field with different intensities. The calculations explain our experimental observations well. © 2005 Wiley Periodicals, Inc. Int J Quantum Chem, 2006
