Excited states identified from molecular movies

WebIn the abiotic world of the early Earth, likely in a chemically excited environment, reservoirs of energy accumulated. In effect, electrons (along with certain key ions) were pumped up chemical hills. Like the water in our analogy, those electrons possessed stored energy. The “problem” was how to release it. Web8 de jan. de 2024 · The calculation does not predict that the excited levels fall back to the ground state. An electron in an excited orbital will, according to this calculation, always stay in this orbital if nothing happens to the system. Because we know that excited states decay, something must happen to the system to induce the decay.
