Does the uncertainty principle provide an estimate of the uncertainty of when a photon is absorbed in a transition corresponding to an energy difference of delta_E=E_final-E_initial? This uncertainty being roughly delta_t= Planck's constant divided by delta_E?
So for example, if delta_E = 5 eV, delta_t = 4.14 fs/5 = 0.83 fs. (1fs = 1 femtosecond = 1e-15 seconds).
