1. The problem statement, all variables and given/known data Suppose we have reason to suspect that a certain quantum object has only three quantum states. When we excited such an object we observe that is emits electromagnetic radiation of three different energies: 2.48 eV (green), 1.91 eV (orange), and 0.57 eV (infrared). Propose two possible energy-level schemes for this system. 2. Relevant equations 3. The attempt at a solution I drew the energy level scheme for the given energies, which I suppose would represent the absorption lines, but what would a second energy-level scheme involve?
