Molecular clusters are ubiquitous constituents of the ambient atmosphere, that can grow into
larger sizes forming new aerosol particles. The formation and growth of small clusters into …

Aerosol particles are important for our global climate, but the mechanisms and especially the
relative importance of various vapors for new particles formation (NPF) remain uncertain …

We investigate the utilization of the domain local pair natural orbital coupled cluster (DLPNO-
CCSD (T)) method for calculating binding energies of atmospherical molecular clusters …

We investigate the basis set convergence of second order Møller Plesset perturbation theory
for the binding energies of 11 strongly hydrogen-bonded clusters relevant to the …

We present a new systematic configurational sampling algorithm for investigating the
potential energy surface of hydrated atmospheric molecular clusters. The algorithm is based …

New particle formation (NPF) is known to be an important source of atmospheric particles
that impacts air quality, hydrological cycle, and climate. Although laboratory measurements …

Oxidation of isoprene, a major biogenic volatile organic compound emitted from forest
canopies, is a potential source of oxalic acid; the dominant species in organic aerosols. We …

Atmospheric molecular clusters, the onset of secondary aerosol formation, are a major part
of the current uncertainty in modern climate models. Quantum chemical (QC) methods are …

Methane sulfonic acid (MSA) is present in substantial concentrations in the gas phase over
oceans and coastal regions. We present an investigation into the contribution of MSA to new …

Highly oxidized multifunctional organic molecules, which span a wide range of low
volatilities, are capable of driving particle formation as well as the initial growth of particles in …
