A transient, excited state of a molecule (e.g., of chlorophyll, upon absorbing light) that can release energy as heat or light (fluorescence) and thus return to the initial (ground) state … The molecule may alternatively assume a slightly more stable, but still excited state (triplet state), with an electron still dislocated as before but with reversed spin. 1, record 1, English, - triple%20state

À l'état fondamental, deux électrons situés dans la même orbitale sont dans un état singulet (les spins sont antiparallèles). Une transition électronique revient à retirer un électron d'une orbitale (n ou [pi]) pour le promouvoir dans une orbitale (généralement [pi]). Lors de la transition électronique, il y a donc deux électrons non appariés qui peuvent être de spin inverse (spins antiparallèles : état singulet) ou de même spin (spins parallèles : état triplet). L'état singulet est, en général, l'état le plus stable. 2, record 1, French, - %C3%A9tat%20triplet

A particular temperature and pressure at which three different phases of one substance can coexist in equilibrium. 3, record 2, English, - triple%20point

In common usage these three phases are normally solid, liquid, and gas, although triple points can also occur with two solid phases and one liquid phase, with two solid phases and one gas phase, or with three solid phases. 3, record 2, English, - triple%20point

D'après la règle des phases, chacune des phases d'un corps pur peut exister dans un certain domaine de température et de pression; l'équilibre entre deux phases a lieu pour une certaine température, déterminée par la valeur de la pression; enfin l'équilibre entre 3 phases existe à un point triple de température et de pression déterminées. 4, record 2, French, - point%20triple

Estado en el que coexisten en equilibrio las fases sólida, líquida y gaseosa de una substancia [y al que] le corresponden una temperatura y presión dadas, características de la substancia considerada. 2, record 2, Spanish, - punto%20triple

El punto triple no es exactamente igual al punto de fusión de la substancia, puesto que en éste el sólido y el líquido están en equilibrio bajo la presión de una atmósfera y en el punto triple lo están bajo su propia presión de vapor. 3, record 2, Spanish, - punto%20triple
