Theoretical Studies of the Energetics of Radicals,ved reactive intermediates such as radicals. Such species have also been found to play significant roles in biological processes. Understanding the role that radicals play in these processes require that the mechanisms by which the reactions take place be understood. Mechanistic understanding of che

Photoacoustic Calorimetry of Radicals and Biradicals,, the enthalpic criterion for distinguishing between concerted and non-concerted thermal rearrangements often involves a comparison between two enthalpies of activation, one experimental and the other hypothetical, attributable to a non-concerted model. Commonly, models involving two non-interacting

We consider here the interrelated concepts of the stability of radicals and of resonance energy, and immediately admit that there is room for considerably more discussion and dispute than space allows here. In the particular, no attempt will be made to ajudicate the different v

There are other physical situations where local thermodynamic equilibrium turns out to be a satisfactory approximation and kinetic information is not important.
