Experiments presented in this contribution demonstrate a heterogeneous source of several chlorine oxides, in particular OClO and ClClO2, from ClO radicals passed over water−ice surfaces at low pressures. ClO radicals were generated in a flow system

Isotopically selected photofragmentation of thermal ClO radicals was studied in the continuous and structured region of the A 2 Π ← X 2 Π transition in the wavelength range 237 λ 2 P 3/2, 1/2 ) and O( 1 D) atoms with a quantum yield of unity. Th

Kinetic measurements as well as B3LYP/ and MP2/6-31G(d,p) calculations provide evidence that carbonyl oxides formed in the gas-phase ozonolysis of alkylated alkenes are an important source of OH radicals. In the gas-phase ozonolysis of propene, cis-2

Nascent products formed in the laser photolysis of the two hypochlorites CH3OCl and HOCl at wavelenths close to the maxima in their absorption spectra have been determined by resonantly enhanced multiphoton ionisation (REMPI) using a time-of-flight (

The OH radical yields generated in the ozonolysis of ethene (ET), propene (PR), cis-2-butene (CB), trans-2-butene (TB), 2,3-dimethyl-2-butene (TME), and isoprene (ISP) in the presence of 20 Vol.% O2 have been determined in a darkened glass reactor at

Chemically and electrochemically generated polyaniline (PANI) was analysed mass spectrometrically using multiphoton ionization at wavelengths of λ = 262 nm and λ = 249 nm, respectively. The mass spectra obtained are characterized by a pattern of si

The rate constant for the title reaction was redetermined using discharge flow technique and mass spectrometric measurements of HOCl consumption. The overall rate constant k = (1.7±0.3)×10−13 cm3 molecule−1 s−1 was obtained and found to be pr

The reactions of HOBr with atomic chlorine (1), with oxygen (2) and with hydroxyl radicals (3) have been investigated at 300 K using the discharge flow technique with mass-spectrometric detection. The rate constants based on HOBr consumption have bee

According to CCSD(T)/TZ + 2P calculations, the decomposition of carbonyl oxide, H2COO to HCO and OH radicals is unlikely in view of an activation enthalpy ΔΔHf0(298) of 31 kcal/mol. However, for dimethylcarbonyl oxide there is a low energy rearrang
