There is an uncertainty principle for energy and time ∆E∆t ≥ ¯h/2 . This relationship can be applied to the excited state energies and their lifetimes of atoms and molecules. a) Show that both sides of the expression for time-energy uncertainty relationship have the same units. b) If the lifetime of a molecule at its excited state is 1 nanosecond, what is the uncertainty of the energy (in eV) of this state? c) If a 10-femtosecond laser is used to...

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.
