How can the energy of an absorbed photon be released without emission of light?
Homework Answers
The energy of a photon can be released without turning it into light via conversion to anothe rform of energy. An example would be an electron absorbing the energy of a photon and then using this energy to go to a higher energy level. This is a way of "emitting" the absorbed energy

true/false 1. Energy of absorbed photon equals energy of emitted photon. 2. Following emission, molecule returns to its lowest energy state by a series of rapid vibrational relaxations. 3. The lifetime of the excited vibrational states is about a femtosecond; the lifetime of the excited electronic state is generally longer than a nanosecond. 4. Photon absorption usually occurs when a molecule is in its ground electronic state.
