I have often wondered what at the molecular level is actually happening. EM is converted into mechanical energy. When the EM radiation hits the molecule how is it converted. Maybe I am seeking a quantum level explanation. Any thoughts?

Ultimately the energy is converted to infra red EM, a higher frequency form of EM, which says to me an excited electron falling back down a level.
