difference of principle
21Franck-Condon principle — The Franck Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to… …
22Correspondence principle — This article discusses quantum theory and relativity. For other uses, see Correspondence principle (disambiguation). In physics, the correspondence principle states that the behavior of systems described by the theory of quantum mechanics (or by… …
23The Pleasure Principle (Gary Numan album) — The Pleasure Principle Studio album by Gary Numan Released September 1979 …
24Cavalieri's principle — Two stacks of coins with the same volume In geometry, Cavalieri s principle, sometimes called the method of indivisibles, named after Bonaventura Cavalieri, is as follows:[1] 2 dimensional case: Suppose two regions in a plane are included between …
25Curtin–Hammett principle — The Curtin–Hammett principle is a principle in chemical kinetics proposed by David Yarrow Curtin and Louis Plack Hammett. It states that, for a reaction that has a pair of reactive intermediates or reactants that interconvert rapidly (as is… …
26Measuring principle — A sender emits a wave which is scattered by an object. The backscattered part of the wave reaches a receiver: The measurement principle of sonar and radar devices …
27Argument principle — In complex analysis, the Argument principle (or Cauchy s argument principle) states that if f ( z ) is a meromorphic function inside and on some closed contour C , with f having no zeros or poles on C , then the following formula holds: oint {C}… …
28Aufbau principle — The Aufbau principle (from the German Aufbau meaning building up, construction : also Aufbau rule or building up principle) is used to determine the electron configuration of an atom, molecule or ion. The principle postulates a hypothetical… …
29Fick principle — Developed by Adolf Eugen Fick (1829 1901), the Fick principle was first devised as a technique for measuring cardiac output. However, its underlying principles may be applied in a variety of clinical situations.The essence of the Fick principle… …
30Reactivity–selectivity principle — In chemistry the reactivity–selectivity principle or RSP states that a more reactive chemical compound or reactive intermediate is less selective in chemical reactions. In this context selectivity represents the ratio of reaction rates. This… …
