Repartitioning of glycerol between levitated and surrounding deposited glycerol/NaNO 3 /H 2 O droplets

Repartitioning of glycerol between levitated and surrounding deposited glycerol/NaNO3/H2O droplets

Repartitioning of semi-volatile organic compounds (SVOCs) between particles is an important process to understand the particle growth and shrinkage in the atmosphere environment. Here, by using optical tweezers coupled with cavity-enhanced Raman spectroscopy, we report the repartitioning of glycerol between a levitated glycerol/NaNO3/H2O droplet and surrounding glycerol/NaNO3/H2O droplets depos...

Excited OH + , H 2 O + , and H 3 O + in NGC 4418 and Arp 220

We report on Herschel/PACS observations of absorption lines of OH, H2O and H3O in NGC 4418 and Arp 220. Excited lines of OH and H2O with Elower of at least 285 and ∼200 K, respectively, are detected in both sources, indicating radiative pumping and location in the high radiation density environment of the nuclear regions. Abundance ratios OH/H2O of 1−2.5 are estimated in the nuclei of both sour...

Spectroscopy of the transition state : Elementary reactions of the hydroxyl radical studied by photoelectron spectroscopy of O 2 ( H 2 O ) and H 3 O 2 2

The transition state regions of the OH1OH→O~P!1H2O and the OH1H2O→H2O1OH reactions are studied by photoelectron spectroscopy of the O~H2O! and H3O2 2 anions and their deuterated analogs. The spectra show resolved vibrational progressions attributed to H-atom vibrational motion in the unstable neutral complexes formed by photodetachment. The positions and intensities of the peaks change markedly...

All - quantum simulations : H 3 O + and HsO 2

Electronic structure calculations using the local density functional method with non-local norm-conserving pseudopotentials, ab initio molecular dynamics simulations, and a novel method of all-quantum simulations, combining a quantum path-integral description of the nuclear degrees of freedom with concurrent electronic structure calculations of the Born-Oppenheimer potential energy surface, wer...
