Abstract

The effect of a homogeneous static electric field on the Li–benzene complex in two configurations, one with a larger Li–C6H6 distance (“loose”) and one with a shorter distance (“tight”), has been investigated. The electric field has the same orientation as the direction of the dipole moments of the complexes. When the direction of the field intensity vector was the same as that of the dipole moment vector, optimization of the complex's geometry in one configuration resulted in switching it to the other one. Reversing the direction of the field then transformed the other configuration back to the original one. This switching behavior was observed beginning with the loose configuration and with the tight configuration. The geometrical and electronic parameters of the complex after four steps of the reversible switching have been calculated for a selected field intensity of 0.005 atomic units (a.u.), that is 0.257 V Å−1.

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.
