Scattering kernel for polyatomic molecules [PDF]

open access: yes, 2005
A polyatomic scattering kernel phenomenologically presented in a previous article is derived from an integral operator formulation. The five parameters involved in the scattering kernel expression are shown to be equal to the accommodation coefficients ...

Statistical collisions of polyatomic molecules [PDF]

open access: yesAsymmetry
In statistical physics, the Gibbs canonical distribution is derived from the microcanonical distribution. In this article, the canonical distribution for pairwise collisions of polyatomic molecules in gases is derived from the microcanonical distribution

VIBRATIONAL AUTOIONIZATION IN POLYATOMIC MOLECULES [PDF]

open access: yesAnnual 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

open access: yesCHIMIA, 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.

Extracting sub-cycle electronic and nuclear dynamics from high harmonic spectra

open access: yesScientific 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 ...

A scalable quantum computing platform using symmetric-top molecules

open access: yesNew 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.

Towards Ultracold Chiral Molecules

open access: yesCHIMIA, 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–
