Mass-analyzed Threshold Ionization Spectrometry with Scrambling Field Optimized for the Study of State-selective Ion Reaction Dynamics

摘要

Mass-analyzed threshold ionization (MATI) technique is optimized to generate substantial amount of state-selected molecular ions sufficient for dynamics study. The main strategy is to stabilize intermediate (n = 100- 200) Rydberg states by l,m-mixing induced by AC field. Electrical jitter inherent in high voltage switching is utilized for this purpose. A related technique to locate the MATI onset is also described.
