Electromagnetically induced transparency in a sodium vapour cell. ... In our experiment, sodium atoms are excited on the D_1-line with laser radiation containing two components with a frequency difference close to that of the two hyperfine ground states of sodium (1.772 GHz). Such an excitation leads to coherent trapping of atomic population in "dark" superpositional states, which dramatically reduces the absorption of light. 3, record 4, English, - vapour%20cell

An atomic absorption spectrophotometer measures element concentrations in solution by spraying (nebulising) the solution into a long narrow hot flame. Light from a hollow cathode lamp, containing the element to be analysed, passes above the long and narrow burner to a monochromator. The monochromator isolates ground state radiation from the hollow cathode lamp. The solution is sprayed into the fuel and air premixing chamber feeding the flame. Free atoms are produced in the flame because of the heat and reducing conditions. If the atoms are the same as the element in the lamp, then light is absorbed. The degree of absorption depends on the amount of that element present in the original solution. The results are compared with standard solutions which allow concentrations to be determined. The technique can be highly precise and accurate. 2, record 6, English, - atomic%20absorption%20spectrometer

Near infrared reflectance spectroscopy (NIRS) is an accurate, precise, and rapid alternative to wet chemistry procedures for determining concentrations of major classes of chemical compounds in organic materials, such as plant foliage. The method utilizes reflectance signals resulting from bending and stretching vibrations in molecular bonds between carbon, nitrogen, hydrogen, and oxygen. Calibration is required to correlate the spectral response of each sample at individual wavelengths to known chemical concentrations from laboratory analyses. 4, record 7, English, - near%20infrared%20reflectance%20spectroscopy

Spectrométrie dans le proche infrarouge(NIRS). C'est actuellement la plus performante des méthodes de prédiction pour mesurer la digestibilité de la matière organique qui permet d’apprécier la valeur énergétique d’un fourrage. Lorsqu'on soumet un ensemble de molécules à un rayonnement lumineux infrarouge(longueurs d’ondes comprises entre 780 et 2500 nm), une partie du rayonnement est absorbée, une autre réfléchie. Les longueurs d’ondes absorbées sont spécifiques à chaque constituant et le degré d’absorption proportionnel à sa concentration. Le spectromètre indique ainsi le spectre réfléchi et permet d’en déduire le spectre d’absorption. C'est une méthode de mesure indirecte. Le spectre d’absorption permet de caractériser un produit exactement comme une empreinte digitale permet d’identifier un criminel par comparaison de «l'empreinte» observée avec une banque de données. 3, record 7, French, - spectroscopie%20de%20r%C3%A9flectance%20dans%20le%20proche%20infrarouge
