Abstract

The spectrum of the intermediate product ascribed to nitrosopentane has been detected in the photolysis of the SO~2~–pentane (RH)–NO mixture. This result has been interpreted in terms of the radical mechanism by assuming the H‐atom abstraction from RH by the excited SO~2~ molecules to be the primary act. The contribution of the singlet and triplet SO~2~ states to the product formation rate and the ratio of the singlet‐to‐triplet rate constants have been evaluated. At NO pressures above 5 torr, the product formation rate significantly deviates from the Stern–Volmer dependence.

The reaction of NO2 with CzF4 was studied at 30Β°, 68", 114O, and 157Β°C by in situ monitoring the infrared absorption bands of the products. The major primary products of the reaction are OzNCFzCFO and FNO. Smaller amounts of CFZO (and presumably NO) are also produced. There was no evidence for other

By allowing dimethyl peroxide ( 10-4M) to decompose in the presence of nitric oxide (4.5 X lOW5M), nitrogen dioxide (6.5 X 10-5M) and carbon tetrafluoride (500 Torr), it has been shown that the ratio kzlkz, = 2.03 f 0.47: CH30 + NO -CH30NO (reaction 2) and CH30 + NO2 -CH30N02 (reaction 2'). Deviatio
