A mechanism for the photolysis of acetone has been derived from experimental data including studies on the photosensitized isomerization of olefines. Dissociation into methyl and acetyl radicals occurs from both the first excited singlet and triplet states; the rate constants for excitation by light of 3130 Å wavelength are 2.5 x 1016 exp ( —16900/RT) and 2.5 x 1010 exp ( — 6400/RT) 1. mole-1 s-1 respectively. At low intensities of absorption, decomposition of acetyl radicals predominates over…

The role of excited states in the gas-phase photolysis of acetaldehyde
The cis-trans isomerization of butene-2 has been used to measure the triplet state yields in the photolysis of acetaldehyde at various wavelengths between 313 and 254 nm over the temperature range 35
The effect of temperature, pressure, and excitation wavelength on the photoluminescence of acetaldehyde vapour
A study of the effect of acetaldehyde, trans-butene-2, and isobutane pressure on the fluorescence and phosphorescence emissions from acetaldehyde vapour has been made. The results have been

The current results are consistent with equilibrium formation of the hydrogen-bonded molecular complex on a short time scale (100 μs) and will have a negligible impact on the atmosphere.

Photolysis of Nitromethane in Gas Phase at 313 nm
Photolysis of nitromethane in gas phase at 313.0 nm was studied at 55°C. Methyl nitrite, formaldehyde, nitrosomethane and NO were obtained as main products, their quantum yields being determined to

Pressure dependent photolysis quantum yields for CH3C(O)CH3 at 300 and 308 nm and at 298 and 228 K.
High yields of T1 (>80%) at the highest pressure in this study indicate that any dissociation from the first excited singlet state occurs in competition with intersystem crossing, and that physical quenching of S1 to the electronic ground (S0) is not a major process at these wavelengths.


Photolysis of Acetone in the Presence of HI and the Decomposition of the Acetyl Radical
Acetone over a range of pressures and temperatures (1.2–15 cm Hg; 126–295°C) was photolyzed with light of 3130 A in the presence of small amounts of hydrogen iodide. The primary process was found to

The effects of pressure, temperature, and exciting intensity on the lifetime of fluorescence of acetone and biacetyl vapor have been investigated. The pressure dependence of the lifetime in acetone
