Quantum‐mechanical calculation of spectral intensity is done for the transitions from a particular vibrational level of the excited state E 1 ∏ u to the discrete vibrational levels and dissociative continuum of the ground state X 1 Σ g +of the Cs 2 molecule. The results are compared with the observed spectra by referring to the conservation of nuclear kinetic energy during the electronic transition.
