This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

Conspectus A generally accepted principle of chemical kinetics is that a reaction will be very
slow at low temperatures if there is an activation barrier on the potential energy surface to …

Nonlinear optical frequency conversion is one of the most versatile methods to generate
wavelength-tunable laser light in the mid-infrared region. This spectral region is particularly …

Novel experimental techniques and computational methods have provided new insight into
the behavior of reactive intermediates in solution. The results of these studies show that …

In recent years, ultra-low temperature chemical kinetic experiments have demonstrated that
some gas-phase reactions are much faster than was previously thought. One example is the …

The recently proposed permutationally invariant polynomial-neural network (PIP-NN) based
Δ-machine learning (Δ-ML) approach (PIP-NN Δ-ML) is a flexible, general, and highly cost …

The hydrogen abstraction reaction of OH+ CH3OH plays a great role in combustion and
atmospheric and interstellar chemistry and has been extensively studied theoretically and …

To understand the origin of interstellar molecules we rely on astrochemical models, the gas-
phase networks of which contain≥ 7000 reactions. However, just a tiny fraction of them …

Intermolecular interactions, stereodynamics, and coupled potential energy surfaces (PESs)
all play a significant role in determining the outcomes of molecular collisions. A detailed …

The rate coefficient for the reaction CH3OH+ OH was determined by means of a relative
method in a simulation chamber under quasi‐real atmospheric conditions (294 K, 1 atm of …
