AI Article Synopsis
- The study examines the ionization of fenchone and camphor using short intense laser pulses through a computational method called time-dependent single center.
- It focuses on understanding photoelectron circular dichroism (PECD) during three-photon resonance and four-photon above-threshold ionization for these molecules.
- The results align well with experimental data and suggest that aligning fenchone and camphor in a specific direction can greatly enhance the observed multiphoton PECD.
Article Abstract
Angle-resolved multiphoton ionization of fenchone and camphor by short intense laser pulses is computed by the time-dependent single center method. Thereby, the photoelectron circular dichroism (PECD) in the three-photon resonance enhanced ionization and four-photon above-threshold ionization of these molecules is investigated in detail. The computational results are in satisfactory agreement with the available experimental data, measured for randomly oriented fenchone and camphor molecules at different wavelengths of the exciting pulses. We predict a significant enhancement of the multiphoton PECD for uniaxially oriented fenchone and camphor.
