62Defining equation (physical chemistry) — For the detailed nature of defining equations see Physical quantity Main article: Physical chemistry In physical chemistry, there are numerous quantities associated with chemical compounds and reactions; notably in terms of amounts of substance,… …
63PSI (computational chemistry) — PSI is an ab initio computational chemistry package originally written by the research group of Henry F. Schaefer, III (University of Georgia). It performs high accuracy quantum computations on small to medium sized molecules. PSI3 is the latest… …
64Method of quantum characteristics — In quantum mechanics, quantum characteristics are phase space trajectories that arise in the deformation quantization through the Weyl Wigner transform of Heisenberg operators of canonical coordinates and momenta. These trajectories obey the… …
65Continuous quantum computation — Two major motivations for studying continuous quantum computation are: Many scientific problems have continuous mathematical formulations. Examples of such formulations are Path integration Feynman Kac path integration Schrödinger equation In… …
66Perturbation theory (quantum mechanics) — In quantum mechanics, perturbation theory is a set of approximation schemes directly related to mathematical perturbation for describing a complicated quantum system in terms of a simpler one. The idea is to start with a simple system for which a …
67Reactivity (chemistry) — For other uses, see Reactivity (disambiguation). Reactivity in chemistry refers to the chemical reactions of a single substance, the chemical reactions of two or more substances that interact with each other, the systematic study of sets of… …
68List of Nobel laureates in Chemistry — The Nobel Prize in Chemistry was established in the 1895 will of Swedish chemist Alfred Nobel. The Nobel Prize in chemistry (Swedish: Nobelpriset i kemi) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various… …
69Analytical chemistry — For the journal, see Analytical Chemistry (journal). Analytical chemistry is the study of the separation, identification, and quantification of the chemical components of natural and artificial materials.[1] Qualitative analysis gives an… …
70Organic chemistry — Structure of the methane molecule: the simplest hydrocarbon compound. Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by… …
