Physical organic chemistry
radical ion
Chemistry; Physical organic chemistry
A radical that carries an electric charge. A positively charged radical is called a "radical cation" (e.g., the benzene radical cation C 6 H 6 .+ ); a negatively charged radical is called a "radical ...
radical pair
Chemistry; Physical organic chemistry
The term is used to identify two radicals in close proximity in solution, within a solvent cage. They may be formed simultaneously by some unimolecular process, e.g., peroxide decomposition, or they ...
radiolysis
Chemistry; Physical organic chemistry
The cleavage of one or several bonds resulting from exposure to high-energy radiation. The term is also often used loosely to specify the method of irradiation ("pulse radiolysis") used in any ...
rate law
Chemistry; Physical organic chemistry
An expression for the rate of reaction of a particular reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) ...
rate-determining step, rate-limiting step
Chemistry; Physical organic chemistry
These terms are best regarded as synonymous with rate-controlling step. However, other meanings that have been given to them should be mentioned, as it is necessary to be aware of them in order to ...
reacting bond rules
Chemistry; Physical organic chemistry
(1) For an internal motion of a molecular entity corresponding to progress over a transition state (energy maximum), any change that makes the motion more difficult will lead to a new molecular ...
reaction coordinate
Chemistry; Physical organic chemistry
A geometric parameter that changes during the conversion of one (or more) reactant molecular entities into one (or more) product molecular entities and whose value can be taken for a measure of the ...
