relaxation 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,… … Universalium
Vibrational energy relaxation — Vibrational energy relaxation, or vibrational population relaxation, is a process in which the population distribution of molecules in vibrationally quantum states of high energy level caused by an external perturbation returns to the Maxwell… … Wikipedia
Spin-lattice relaxation time — Spin lattice relaxation time, known as T1, is a time constant in Nuclear Magnetic Resonance and Magnetic Resonance Imaging. It is named in contrast to T2, the spin spin relaxation time.T1 characterizes the rate at which the longitudinal Mz… … Wikipedia

Fluorescence — Fluorescent minerals emit visible light when exposed to ultraviolet light Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation of a different wavelength.[1] It is a form of luminescence.… … Wikipedia
photochemical 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… … Universalium
Spontaneous emission — is the process by which a light source such as an atom, molecule, nanocrystal or nucleus in an excited state undergoes a transition to the ground state and emits a photon. Spontaneous emission of light or luminescence is a fundamental process… … Wikipedia
Franck-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… … Wikipedia
Population inversion — In physics, specifically statistical mechanics, a population inversion occurs when a system (such as a group of atoms or molecules) exists in state with more members in an excited state than in lower energy states. The concept is of fundamental… … Wikipedia
