51Hot band — In molecular vibrational spectroscopy, a hot band (or hot transition) is a transition between two states of a single normal mode of vibration, neither of which is the overall ground state.[1] In infrared or Raman spectroscopy, hot bands refer to… …
52Davydov soliton — Side view of an α helix of alanine residues in atomic detail. Protein α helices provide substrate for Davydov soliton creation and propagation. Davydov soliton is a quantum quasiparticle representing an excitation propagating along the protein α… …
53BKS theory — The Bohr Kramers Slater (BKS) theory [N. Bohr, Collected Works, J. Kalckar, ed. North Holland, Amsterdam, etc., 1985, Vol. 5, pp. 3 216.] [J. Mehra and H. Rechenberg, The historical development of quantum theory, Springer Verlag, New York, etc.,… …
54Atomic orbital — The shapes of the first five atomic orbitals: 1s, 2s, 2px, 2py, and 2pz. The colors show the wave function phase. These are graphs of ψ(x,y,z) functions which depend on the coordinates of one electron. To see the elongated shape of ψ(x,y,z)2… …
55Spectroscopy — Analysis of white light by dispersing it with a prism is example of spectroscopy. Spectroscopy ( …
56Fluorescence spectroscopy — aka fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample. It involves using a beam of light, usually ultraviolet light, that excites the electrons in molecules of certain compounds …
57Induced gamma emission — In physics, induced gamma emission (IGE) refers to the process of fluorescent emission of gamma rays from excited nuclei, usually involving a specific nuclear isomer. It is analogous to conventional fluorescence, which is defined to be the… …
58N-Electron Valence state Perturbation Theory — In quantum chemistry, N Electron Valence state Perturbation Theory (NEVPT) is a perturbative treatment applicable to multireference CASCI type wavefunctions. It can be considered as a generalization of the well known second order Møller Plesset… …
59Quark–gluon plasma — A QGP is formed at the collision point of two relativistically accelerated gold ions in the center of the STAR detector at the relativistic heavy ion collider at the Brookhaven national laboratory. A quark–gluon plasma …
60n-electron valence state perturbation theory — In quantum chemistry, n electron valence state perturbation theory (NEVPT) is a perturbative treatment applicable to multireference CASCI type wavefunctions. It can be considered as a generalization of the well known second order Møller Plesset… …
