Abstract

Kinetic energy release values T(50%) for the collision-induced formation of the p-nitrobenzoate and p-nitrophenoxide anions from the molecular anions of p-O₂NC₆H₄COOC₆H₄R-p and p-O₂NC₆H_4- OC₆H₄R-p respectively are small and relatively insensitive to the nature of the substituent R.T (50%) values for the elimination of R? (R = alkyl) from O₂NC₆H₄OR molecular anions range from 0.4 to 0.01 eV, and are dependent upon the nature of R and upon its number of active oscillators.
