2) You have a group of identical molecules, each with energy levels at 0.3eV, 1.0eV, 1.3eV, 1.5eV, 2.3eV, and 2.5eV. There are no other levels. Each molecule starts in its ground state. A) You illuminate this atom with a bright source of infrared radiation with a 1240nm wavelength. Which is the most likely excited state which will result? Why? B) Closer examination reveals that eventually every single excited state is attained by at least some of the molecules. For EACH excited state (other than your answer to part A), give an account of how it might eventually become populated. (Energy must be exactly conserved at every step, but there can be a multi-step process. The bright infrared source remains on throughout the experiment, but no other light is coming in. Words or symbols or diagrams are all fine, but if you use symbols/diagrams, you will probably need clarifying words here and there.)
