Abstract

The photoionization mass spectra of methyl and ethyl nitrate were investigated. Using the appearance potential of $C 2 H$ $5+$ from $C 2 H 5 O N O 2$ , combined with well established thermodynamic data, the heat of formation of $N O 3$ was found to be 10.8 $±$ 1.0 kcal/mole. Various negative ions can be formed by the transfer of “nearly-zero-energy” electrons from electronically excited argon atoms to a series of parent nitro and nitrate molecules. Consideration of the relative energetics of these reactions leads to limiting values for the electron affinities: E.A. (NO) $≥$ 2.90 eV; 2.15 $≤$ E.A. ( $N O 2 ±≤2.4$ eV.
