KnowraEinstein coefficientsLinked fromLinked fromThe 8 pages that link to Einstein coefficients, each with the reason it gives.All 8Related 7Narrower topic 1Stimulated emissionRelated: They quantify the transition rates that determine how stimulated emission competes with absorption.21-centimeter lineRelated: They quantify the weak radiative transition responsible for the line.Emission spectrumRelated: They quantify how populations and radiation conditions shape emitted spectral features.Population inversionRelated: Their relations show why equal-level populations do not generally produce optical gain.Atomic energy levelRelated: They describe the rates of spontaneous and light-induced transitions between atomic levels.Spontaneous emissionRelated: The coefficient A gives the rate of spontaneous emission for a transition.Atomic physicsRelated: They quantify the main ways atoms exchange energy with radiation.
