When molecule overcomes an energy barrier in order to change ints conformation between two energetically equivalent states, does it then release the absorbed energy fully back as a light or does ir start moving faster and bouncing to other molecules? Simply put, is there any form of process in effect equivalent to energy dissipation going to occur?
Would annisolated box filled with half excited molecules and half relaxed keep its excited/relaxed ratio or would it become warmer and the ratio would shift to relaxed?
