A molecule in its first excited state will spontaneously decay to the ground state by emitting a photon. For two samples of two different molecules the lifetime, ?, of this process is 11 ps and 3.5 ns. Calculate the minimum FWHM, Γ, of the resulting spectral lines of the two samples. Explain your answer in terms of the uncertainty principle.

The Width of Spectral Lines: The average time after excitation at which a group of atoms radiate is called the lifetime, t, of an excited state. Due to Heisenberg uncertainty principle, the excited state energy has a corresponding uncertainty of DE, which is responsible for the width of spectral lines known as natural linewidth (natural broadening). If t = 1.0´10-8 s, calculate the energy uncertainty of the excited sate. Compute the natural linewidth Df of light due to transition from...

1. A molecule has a ground state and two excited electronic energy levels all of which are not degenerate. The energies of the three states are E = 0, E1 = 1x10^-20 J and E2 = 2x10^-20 J. Calculate the partition functions at 298 and 1000K. What fraction of the molecules is in each of the three states at these temperatures?
