At the same time, the enthalpy change of 212 kJ/mol for Tempo trapping methyl radical, namely O-〓 bond dissociation energy has been also obtained. This value is close to that of nitrous acid ester and far less than that of nitric acid ester. It is probably due to the relatively strong electron withdrawing capability of nitryl group.

同时我们还测得了甲基自由基与Tempo的反应的焓变，即O—〓键离解能为212 kJ／mol，它接近于亚硝酸甲酯中C—O键的离解能，而小于硝酸甲酯中的键离解能，这可能和硝酸根的吸电子能力较大有关。
