The N+ and N+2 products of the thermal-energy reaction of He+ with 14N2 and 15N2 have been examined by mass spectrometry and the emission from the product C2Σ+u state of 14N+2 has been investigated by optical spectrometry. A strong isotope effect is

A systematic study of ion—molecule reactions has been done during the past several years in the NOAA flowing afterglow apparatus. These studies include the investigation of reactions involving unstable neutral reactants such as atomic hydrogen, ato

Rates for some thermal ion-molecule reactions of considerable importance in the ionosphere have been measured by a flowing, steady state afterglow technique. Results include: N+ + O2 → NO+ + O k = 5 × 10−10 cm3 sec−1N2+ + O2 → O2+ + N2k = 4

The rate coefficient for the reaction N 2 + + O → NO + + N at 300°K has been measured to be k 1a = 2.5(± 1) × 10 −10 cm 3 se −1 . No previous laboratory measurements of this reaction rate at thermal energies have been reported. This reaction

A new mechanism for the loss of terrestrial helium is proposed. The mechanism involves the reaction He(23S) + O → He + O+ + e This reaction is very likely the dominant helium metastable loss process in the atmosphere. It is speculated that the exce

It is found that charge-transfer on NO − 2 with Cl 2 is fast at thermal energy. The Cl − 2 ion reacts with NO 2 to produce Cl − and NO 2 Cl, and SH − charge-transfers rapidly with both Cl 2 and NO 2 . From the exothermicities implied it is de

Preliminary measurements of reaction rates for loss of thermal helium ions in reaction with molecular oxygen and nitrogen establish rather conclusively that the helium ions in the ionosphere will be lost in reaction with molecular nitrogen rather tha

Water vapor plays a central role in the ion chemistry of the atmosphere below 80 km. The hydronium ions H 3 O + ·nH 2 O, are among the most stable atmospheric positive ions. The paths that convert O 2 + and NO + to hydronium ions are well understood
