The magnitudes of the deuterium isotope effects and beta when protonion is rate limiting suggest the transition state for the proton transfer to involve tunneling and to be early. With the X-ray structure of bovine catalase (Rossmann et al, ref 5), the imidazole bases of His234 and His304...

(see Chapter 8on atoms). It is the repulsion between the orbiting electrons of one atom and the next that keeps them apart and keeps matter stiff. In the simplest atom, hydrogen, which consists of a single proton orbited by an electron, the gravitational force between them is about 1040,...
Ab initio study of the structure of guanine-cytosine base pair conformers in gas phase and polar solvents The structure and energetics of the base pairing and proton transfer in the Watson-Crick type of guanine-cytosine base pair are studied by the HF/MINI-1 me... J Florián,JL&S Scheine...

A first-order four-body perturbation theory is developed to calculate both the differential and integral cross-sections for K-shell charge exchange from multi-electron atomic targets to the 1s bound state of the fast proton projectiles. The correct boundary conditions are incorporated in the formalism...
Controlling Factors in the Rates of Oxidation of Anilines and Phenols by Triplet Methylene Blue in Aqueous Solution The observed rate constants are also well modeled when aniline oxidation potentials derived computationally are used. For phenols, the proton-coupled electron transfer rate constants were ...
We suggest that if the correlated positron-electron peaks seen in superheavy-ion collisions arise from the decay of a new neutral particle with a mass of about 1.7 MeV, its spin-parity is 1u2212. We show that it then can be produced by the interaction of three photons, with a large cro...
