Vibrational transition — A vibrational transition is an abrupt change in vibrational energy in quantum physics. Like all other properties of a quantum particle, vibrational energy is quantized, meaning it can only equal certain discrete values, which correspond to… … Wikipedia
resonant frequency — The natural vibrational frequency of a body. It is the frequency of a source of vibration that is exactly the same as the natural vibration frequency of the structure … Aviation dictionary
Rotational-vibrational coupling — occurs when the rotation frequency of an object is close to or identical to a natural internal vibration frequency. The animation on the right shows a simple example. The motion depicted in the animation is for the idealized situation that the… … Wikipedia
spectroscopy — spectroscopist /spek tros keuh pist/, n. /spek tros keuh pee, spek treuh skoh pee/, n. the science that deals with the use of the spectroscope and with spectrum analysis. [1865 70; SPECTRO + SCOPY] * * * Branch of analysis devoted to identifying… … Universalium
Kinetic isotope effect — The kinetic isotope effect (KIE) is the ratio of reaction rates of two different isotopically labeled molecules in a chemical reaction. It is also called isotope fractionation, although this term is somewhat broader in meaning. A KIE involving… … Wikipedia
analysis — /euh nal euh sis/, n., pl. analyses / seez /. 1. the separating of any material or abstract entity into its constituent elements (opposed to synthesis). 2. this process as a method of studying the nature of something or of determining its… … Universalium
Motional narrowing — In physics and chemistry, motional narrowing is a phenomenon where a certain resonant frequency has a smaller linewidth than might be expected, due to motion in an inhomogeneous system.[1] Example: NMR spectroscopy A common example is NMR.[1] In… … Wikipedia
Resolved sideband cooling — is a laser cooling technique that can be used to cool strongly trapped atoms to the quantum ground state of their motion. The atoms are usually precooled using the Doppler laser cooling. Subsequently the resolved sideband cooling is used to cool… … Wikipedia
Vibration theory of olfaction — The Vibration theory of smell proposes that a molecule s smell character is due to its vibrational frequency in the infrared range. The theory is opposed to the more widely accepted shape theory of olfaction, which proposes that a molecule s… … Wikipedia
Rigid rotor — The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3 dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the… … Wikipedia
Zero-phonon line and phonon sideband — The zero phonon line and the phonon sideband jointly constitute the line shape of individual light absorbing and emitting molecules (chromophores) embedded into a transparent solid matrix. When the host matrix contains many chromophores, each… … Wikipedia
