21Fluorescence 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 …
22photochemical reaction — Chemical reaction initiated by absorption of energy in the form of visible (light), ultraviolet, or infrared radiation. Primary photochemical processes occur as an immediate result, and secondary processes may follow. The most important example… …
23radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… …
24relaxation phenomenon — ▪ physics and chemistry Introduction in physics and chemistry, an effect related to the delay between the application of an external stress to a system that is, to an aggregation of matter and its response. It may occur in nuclear, atomic,… …
25Gas dynamic laser — (GDL) is laser based on differences in relaxation velocities of molecular vibrational states.The laser medium gas has such properties that an energetically lower vibrational state relaxes faster than a higher vibrational state,thus a population… …
26Ghedee — (or Gheede) (pronounced|ˈʒiː.iː.diː) is the name of a secret society of energy workers in the coastal region of West Africa, primarily in The Ivory Coast and Liberia. The primary focus of Ghedee practice is physical, mental, and emotional healing …
27Jablonski diagram — by squiggly arrows. The vibrational ground states of each electronic state are indicated with thick lines, the higher vibrational states with thinner lines.Radiative transitions involve the absorption, if the transition occurs to a higher energy… …
28Molecule — 3D (left and center) and 2D (right) representations of the terpenoid molecule atisane A molecule (pronounced  …
29Absorption spectroscopy — An overview of electromagnetic radiation absorption. This example discusses the general principle using visible light as a specific example. A white beam source – emitting light of multiple wavelengths – is focused on a sample (the complementary… …
30Chemiluminescence — A chemoluminescent reaction carried out in an erlenmeyer flask producing a large amount of light. Chemiluminescence (sometimes chemoluminescence ) is the emission of light with limited emission of heat (luminescence), as the result of a chemical… …
