N2O5 at water surfaces: binding forces, charge separation, energy accommodation and atmospheric implications

26-Jun-2018 | Barak Hirshberg; Estefanía Rossich Molina; Andreas W. Götz; Audrey D. Hammerich; Gilbert M. Nathanson; Tim ..., Physical Chemistry Chemical Physics, 2018

Interactions of N2O5 with water media are of great importance in atmospheric chemistry and have been the topic of extensive research for over two decades. Nevertheless, many physical and chemical properties of N2O5 at the surface or in bulk water are unknown or not microscopically understood. ...

Unimolecular reaction of acetone oxide and its reaction with water in the atmosphere [Chemistry]

12-Jun-2018 | Bo Long; Junwei Lucas Bao; Donald G. Truhlar, Proceedings of the National Academy of Sciences current issue, 2018

Obtaining rate constants and tropospheric lifetimes of Criegee intermediates is of critical significance for atmospheric modeling. We report calculations that can produce quantitative rate constants by variational transition state theory with corner-cutting tunneling based on implicit potential ...

Atmospheric Chemistry of E- and Z-CF3CH═CHF (HFO-1234ze): OH Reaction Kinetics as a Function of Temperature and UV and IR Absorption Cross Sections

20-Oct-2017 | María Antiñolo; Iván Bravo; Elena Jiménez; Bernabé Ballesteros; José Albaladejo, Journal of Physical Chemistry A, 2017

We report here the rate coefficients for the OH reactions (kOH) with E-CF3CH═CHF and Z-CF3CH═CHF, potential substitutes of HFC-134a, as a function of temperature (263–358 K) and pressure (45–300 Torr) by pulsed laser photolysis coupled to laser-induced fluorescence techniques. For the E-isomer, ...
