Gas phase ozonolysis of camphene in the presence of SO2
Klaus Jay,Ludwig Stieglitz +1 more
TL;DR: In the presence of SO 2 (0.4 mg/10 l), the product ratio rises to 8:1 as mentioned in this paper, which seems to indicate that the Criegee diradical oxidizes SO 2 to SO 3 prior to cyclization to dioxirane.

TL;DR: In this article, the outflow of the south Asian summer monsoon and its influence on the composition of the Asian Monsoon Anticyclone (AMA) in the upper troposphere over the eastern Mediterranean and the Arabian Peninsula were investigated.

Sensitivity of sulphur dioxide oxidation in sea salt to nitric acid and ammonia gas phase concentrations
Nicola A. Clegg,Ralf Toumi +1 more
TL;DR: In this article, the role of sea-salt aerosol in the sulphur dioxide budget is investigated using a steady state box model, which simulates, for certain species, the condensation onto, and chemical reactions within, deliquescent sea salt particles.

Both Sides Now
TL;DR: Etude de la chimie atmospherique suivant deux approches: 1) des etudes en laboratoire de la thermodynamique and de la cinetique des procedes intervenant dans l'acidification de l'eau des nuages and 2) des mesures directes sur le terrain for determiner la composition des nages and elucider les mecanismes de formation des constituants as discussed by the authors.
Journal ArticleDOI
Negative ion photoelectron spectra of ISO3-, IS2O3-, and IS2O4- intermediates formed in interfacial reactions of ozone and iodide/sulfite aqueous microdroplets.
TL;DR: The obtained intrinsic molecular properties of these anionic intermediates and neutral radicals should be useful to help understand their photochemical reactions in the atmosphere.

The importance of atmospheric ozone and hydrogen peroxide in oxidising sulphur dioxide in cloud and rainwater
TL;DR: In this paper, the authors used the experimental data to calculate the rate of sulphate formation in water droplets under atmospheric conditions for each of the three oxidants, i.e., ozone, ozone and hydrogen peroxide.

Mechanism of the homogeneous oxidation of sulfur dioxide in the troposphere
TL;DR: In this article, an evaluation of the existing kinetic data related to the elementary, homogeneous reactions of SO 2 within the troposphere is made, and a set of preferred values of the rate constants for these reactions is presented.

Kinetics of the oxidation of sulfite by hydrogen peroxide in acidic solution
M. R. Hoffmann,J. O. Edwards +1 more
TL;DR: In this article, the authors investigated the kinetics of sulfite by hydrogen peroxide over the pH range 4-8 and showed that the reaction probably proceeds via a nucleophilic displacement by H 2O_2 on HSO_3^- to form a peroxomonosulfurous acid intermediate which then undergoes a rate-determining rearrangement.
