When electromagnetic radiation in the ultraviolet and visible regions passes through a compound containing multiple bonds, a portion of the radiation is usually absorbed by the compound. Just how much of the radiation is absorbed depends on the wavelength of the radiation and the structure of the compound. The absorption of radiation is caused by the substraction of energy from the radiation beam when electrons in orbitals of lower energy are excited into orbitals of higher energy.... The heme enzymes catalase and peroxidase have distinctive absorption spectra due to their heme prosthetic groups. 3, record 2, English, - absorption%20spectrum

Le spectre d’absorption d’un composé reflète sa capacité d’absorber la lumière en fonction de la longueur d’onde. Quand un photon frappe un atome ou une molécule capable d’absorber la lumière à une longueur d’onde donnée, l'énergie est absorbée par certains des électrons et l'atome ou la molécule passe à un état excité, riche en énergie. Seuls les photons de certaines longueurs d’onde peuvent exciter un atome ou une molécule donnée, l'excitation des molécules n’ étant pas continue mais quantifiée; ceci veut dire que l'énergie lumineuse n’ est absorbée que par fractions discrètes sur la base d’une loi de "tout ou rien", conduisant au terme de quantum. 2, record 2, French, - spectre%20d%26rsquo%3Babsorption

Le maser("Microwave Amplification by Stimulated Emission of Radiation") à hydrogène est une horloge atomique extrêmement stable basée sur l'atome d’hydrogène. Il a été inventé par Kleppner et Ramsey en 1960 à l'université de Harvard. Le principe de fonctionnement est semblable à celui du LASER sauf que la radiation émise est une radiation micro-onde et non pas optique. Le maser à hydrogène est utilisé principalement en radioastronomie et en géodésie comme horloge pour la synchronisation de radiotélescopes utilisant la technique du VLBI(Very Long Base Interferometry). Il est utilisé également pour la poursuite des sondes planétaires(Deep Space Tracking). Dans le futur, il pourrait être utilisé dans les systèmes de navigation par satellite de type GPS à cause de sa très grande stabilité(cf l'avenir du temps atomique). 3, record 6, French, - maser%20%C3%A0%20hydrog%C3%A8ne%20passif

All atoms are about the same size, and this fact is a clue to the nature of their structure. The atomic diameter is about 2 X 10[superscript] -8 cm (2 hundred-millionths of a centimeter).
