An Ab Initio Study of the Kinetics of the Reactions of Halomethanes With the Hydroxyl Radical. 1. CH 2 Br 2

April 1, 2000

Author(s)

F Louis, Carlos A. Gonzalez, Robert E. Huie, Michael J. Kurylo III

Ab initio calculations using the M ller-Plesset perturbation theory were carried out on the H-atom abstraction reaction from dibromomethane by hydroxyl radical attack. Geometry optimization and vibrational frequency calculations at the MP2 level were

Atmospheric Lifetimes and Global Warming Potentials of Hydrofluoroethers: Reactivity Towards OH, UV Spectra, and IR Absorption Cross-Sections

December 1, 1999

Author(s)

Vladimir L. Orkin, E Villenave, Robert E. Huie, Michael J. Kurylo III

The rate constants for the reactions of OH radicals with the fluorinated ethers, CHF 2-OCHF 2 (HFOC-134), and CF 3CH 2-O-CH 2CF 3 (HFOC-356mff), were measured using the flash photolysis resonance fluorescence technique over the temperature range 277 K to

Reduction Potentials of SO 3 -, SO 5 .-, And S 4 O 6 . 3- Radicals in Aqueous Solution

November 1, 1999

Author(s)

T N. Das, Robert E. Huie, Pedatsur Neta

Reduction potentials of the SO- 3 -, SO 5 -, and S 4O 6 3- radicals in aqueous solutions are measured by pulse radiolysis at 294 K. These radicals are produced by reaction of OH or N 3 radicals with sulfite, peroxymonosulfate, and thiosulfate anions

Reduction Potential of the Sulfhydryl Radical. Pulse Radiolysis and Laser Flash Photolysis Studies of the Formation and Reactions of SH and HSSH in Aqueous Solutions

July 1, 1999

Author(s)

T N. Das, Robert E. Huie, Pedatsur Neta, S Padmaja

Formation and reactions of the SH/ S and HSSH /HSS 2- radicals in aqueous solutions have been studied by excimer laser flash photolysis and by pulse radiolysis. Acidic H 2S solutions with 193-nm laser pulses produce a transient species with λ max at 240 nm

SO x Radical Monoanions--Reactions in Solution and in the Gas Phase

February 1, 1999

Author(s)

Robert E. Huie, L W. Sieck

Sulfur dioxide, SO 2, is a major air pollutant and a natural trace atmospheric constituent. The major anthropogenic source of SO 2 is the combustion of fossil fuels, although much also arises from scrubbing natural gas and from smelting sulfide ores (1)

Kinetics and Mechanism of the Reaction of NH 2 with O 2 in Aqueous Solutions

July 15, 1998

Author(s)

B Laszlo, Z B. Alfassi, Pedatsur Neta, Robert E. Huie

The reaction of NH 3 with OH or SO 4 radicals produces the aminyl radical, NH 2. Pulse radiolysis and laser flash photolysis techniques were utilized to study the formation of this radical, its absorption spectrum, its reaction with O 2, and the mechanism
