| specific optical dispersion | <microscopy> The difference between the refractive indices of light of two different wavelengths, both indices measured at the same temperature, the difference being divided by the specific gravity also measured in the same medium at the test temperature. For convenience, the specific dispersion value is multiplied by ten. (05 Aug 1998) |

| dispersion | <microscopy> The variation of refractive index with colour (or wave-length) of light. The spreading of white light into its component colours when passing through a glass prism is due to dispersion which, in turn, is due to the fact that the refractive index of transparent substances is lower for long wavelengths than for-short wavelengths. A measure of dispersion is defined as: nD - 1 v= nF-nC where nD = refractlve index at 589 nm (yellow), nF = 486 nm (blue), nC = 656 nm (red). (05 Aug 1998) |
| dispersion colloid | A colloidal solution in which the dispersed phase can be concentrated by centrifugation. Synonym: dispersion colloid, molecular dispersed solution. (05 Mar 2000) |
| dispersion force | Forces of attraction between atoms or nonpolar molecules that result from the formation of induced dipoles. Sometimes referred to as London dispersion forces. Important in the DLVO theory of colloid flocculation and thus in theories of cell adhesion. (18 Nov 1997) |
| dispersion medium | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
| dispersion phase | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
| dispersion relation | <radiobiology> For a given wave, the dispersion relation relates the temporal frequency of a wave (w, or omega) to its wavenumber k and other physical quantities characteristic of the system. Dispersion relations can be quite simple (for example, w = k c for light, c being the speed of light), and they can also be quite complex, with interesting mathematical structure. The dispersion relation and its mathematical structure provide important information about the wave, including the phase and group velocities. Note that the meaning of dispersion relation is different in plasma physics than in other fields. (09 Oct 1997) |
| dispersion staining | <microscopy> A procedure involving central or annular stops in the objective back focal plane to induce coloured images of transparent particles mounted in liquids with indices matching the particle at a wavelength in the visible. The particle and liquid should possess very different dispersion curves for best colours. (05 Aug 1998) |
| optical rotatory dispersion | The method of measuring the dispersion of an optically active molecule to determine the relative magnitude of right- or left-handed components and sometimes structural features of the molecule. (12 Dec 1998) |
| temporal dispersion | Asynchronous repolarization of myocardial fibres that predisposes to abnormal current flow and ectopic rhythms (especially with bradyarrhythmias). (05 Mar 2000) |
| london dispersion forces | <chemistry> The forces that exist in nonpolar molecules that involve an accidental dipole that induces a momentary dipole in a neighbor. (09 Jan 1998) |
