Ultrafast IR laser control of photodissociation: single- vs. multi-pulse schemes
文献情報
Analytical laser pulses are designed to break the H–Co bond of HCo(CO)4 in the electronic ground state. The potential energy surface is taken from a pseudo-triatomic model of this compound. Single- and two-pulse dissociations are shown to be equally efficient in their ability to dissociate the molecule within two picoseconds at moderate field strengths. The isotope TCo(CO)4 is considered as well and results of a three-pulse laser interaction are presented. Laser selective isotope separation is demonstrated to be feasible over a wide range of frequencies using a single driving field.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
