Flowing afterglow measurements are reported which provide rate constants and product identifications at 298 ± 2 K for the gas-phase reactions of OH− with CH3OH, C2H5OH, CH3OCH3, CH2O, CH3CHO, CH3COCH3, CH2CO, HCOOH, HCOOCH3, CH2=C=CH2, CH3—C≡CH, and C6H5CH3. The main channels observed were proton transfer and solvation of the OH−. Hydration with one molecule of H2O was observed either to reduce the rate slightly and lead to products which are the hydrated analogues of the "nude" reaction, or to stop the reaction completely, k ≤ 10−12 cm3 molecule−1 s−1. The reaction of OH−•H2O with CH3—C≡CH showed an uncertain intermediate behaviour.

The strategy of synthesizing diazeniumdiolates (X–N(O)=NO−) through the coexistence of nitric oxide and alkoxides (RO−) was introduced by Wilhelm Traube 120 years ago. Today, despite the wide use of diazeniumdiolate derivatives to release nitric oxide in the treatment of cancer, the first step of the reaction mechanism for diazeniumdiolate synthesis remains a mystery and is thought to be complex. We have studied the gas-phase reactions of nitric oxide with alkoxides at room temperature. An electron-coupled hydrogen transfer is observed, and the radical anion HNO− is the only ionic product in these reactions. HNO− can further react with nitric oxide to form N2O and HO−.

Cathode Ray Tube

A mass spectroscope capable of recording the trend of many chemical species in rapid gas-phase reactions is described. The instrument represents a departure from analytical mass spectrometric practice by using a molecular streaming source, rapid electric scanning, an electron multiplier ion detector amplifier, and a cathode ray tube display. A 40 peak spectrum can be scanned in five milliseconds and recorded by a motion picture camera. A few results obtained with this instrument in the study of diethyl ether cool flames are given.

The new GMPE method was introduced to derive the macroscopic rate coefficients for complex gas-phase reactions from the time-resolved species profiles obtained from the master equation (ME) solutions.
