1Stokes' law (sound attenuation) — Stokes derived law for attenuation of sound in Newtonian liquid [ Stokes, G.G. On the theories of the internal friction in fluids in motion, and of the equilibrium and motion of elastic solids , Transaction of the Cambridge Philosophical Society …
2Stokes shift — is the difference (in wavelength or frequency units) between positions of the band maxima of the absorption and emission spectra (fluorescence and Raman being two examples) of the same electronic transition. It is named after Irish physicist… …
3Stokes boundary layer — in a viscous fluid due to the harmonic oscillation of a plane rigid plate. Velocity (blue line) and particle excursion (red dots) as a function of the distance to the wall. In fluid dynamics, the Stokes boundary layer, or oscillatory boundary… …
4stokes' law — noun Usage: usually capitalized S Etymology: after Sir George G. Stokes 1. : a law in physics: the frequency of luminescence excited by radiation does not exceed that of the exciting radiation 2. : a law in physics: the force required to move a… …
5Stokes drift — For a pure wave motion in fluid dynamics, the Stokes drift velocity is the average velocity when following a specific fluid parcel as it travels with the fluid flow. For instance, a particle floating at the free surface of water waves,… …
6Stokes lines — ▪ physics radiation of particular wavelengths present in the line spectra associated with fluorescence and the Raman effect (q.v.), named after Sir George Gabriel Stokes, a 19th century British physicist. Stokes lines are of longer… …
7Stokes' law — Physics. 1. the law that the force that retards a sphere moving through a viscous fluid is directly proportional to the velocity of the sphere, the radius of the sphere, and the viscosity of the fluid. 2. the law that the frequency of… …
8Coherent anti-Stokes Raman spectroscopy — Coherent anti Stokes Raman spectroscopy, also called Coherent anti Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures… …
9Coherent Stokes Raman spectroscopy — (CSRS pronounced as scissors ) is a form of spectroscopy used primarily in chemistry, physics and related fields. It is closely related to Raman spectroscopy and lasing processes. It is very similar to Raman spectroscopy but involves a lasing… …
10an|ti-Stokes line — «AN tee STOHKS», a line in a spectrum of the same, or higher, frequency as that of the exciting light. It is due to a vibrating molecule s absorption of a light quantum. ╂[see etym. under Stokes law (Cf. ↑Stokes law)] …
