Abstract

The effect of dissociation on the reactivity and inhibition capacity of nitrophenol isomers towards ortho-positronium atom has been investigated in methanol and methanol containing 0.5 M NaOH solutions. It has been found that as a result of dissociation the rate constants (KPs) and the inhibition coefficients (σ) decreased significantly in all cases. A comparison of the rate constants of the scavenging of spur electrons with the inhibition coefficients also suggests that the scavenging of positrons plays an important role in the inhibition processes. In the case of the ortho isomer our results strongly support the idea of the stabilizing effect of the intramolecular hydrogen bond between the OH and NO2 groups of the neutral molecule.
