On the determination of Lennard-Jones parameters for polyatomic molecules [PDF]
, 2022 Characterizing the key length and energy scales of intermolecular interactions, Lennard-Jones parameters, i.e., collision diameter and well depth, are prerequisites for predicting transport properties and rate constants of chemical species in dilute ...

Extracting sub-cycle electronic and nuclear dynamics from high harmonic spectra
Scientific Reports, 2021 We present a new methodology for measuring few-femtosecond electronic and nuclear dynamics in both atoms and polyatomic molecules using multidimensional high harmonic generation (HHG) spectroscopy measurements, in which the spectra are recorded as a ...

VIBRATIONAL AUTOIONIZATION IN POLYATOMIC MOLECULES [PDF]
Annual Review of Physical Chemistry, 2005 ▪ Abstract The vibrationally autoionizing Rydberg states of small polyatomic molecules provide a fascinating laboratory in which to study fundamental nonadiabatic processes. In this review, recent results on the vibrational mode dependence of vibrational autoionization are discussed. In general, autoionization rates depend strongly on the character of

Efficient Semiclassical Evaluation of Electronic Coherences in Polyatomic Molecules
CHIMIA, 2022 Exposing a molecule to intense light pulses may bring this molecule to a nonstationary quantum state, thus launching correlated dynamics of electronic and nuclear subsystems.

A scalable quantum computing platform using symmetric-top molecules
New Journal of Physics, 2019 We propose a new scalable platform for quantum computing (QC)—an array of optically trapped symmetric-top molecules (STMs) of the alkaline earth monomethoxide (MOCH _3 ) family.

A Review on BGK Models for Gas Mixtures of Mono and Polyatomic Molecules
Fluids, 2021 We consider the Bathnagar–Gross–Krook (BGK) model, an approximation of the Boltzmann equation, describing the time evolution of a single momoatomic rarefied gas and satisfying the same two main properties (conservation properties and entropy inequality).

Towards Ultracold Chiral Molecules
CHIMIA, 2018 Atoms can be cooled and trapped efficiently with the help of lasers. So-called Doppler cooling takes advantage of momentum transfer upon absorption and emission of photons and of Doppler shifts to facilitate effectively closed optical absorption–
