✦ Synopsis

The lowest order relativistic corrections to the electronic energies have been computed for the B 1E u state of H 2 in the interval 1.0 ~< R ~< 30 a 0. The total correction at the equilibrium separation, R = 2.43 a o amounts to -2.126 cm-1. The absolute shifts of the vibrational levels of H 2 change monotonically with v for v ~< 27 from -2.090 to -1.538 cm-1 as compared with the -1.918 cm-1 shift of the dissociation limit. The computed shifts are used to place the c = 0 levels of H a and D 2 on a absolute energy scale and a comparison with experiment is performed.

We have used the e\pc:imental energy levels of the B state of Na2 to determine the shape of the potentL1 curve. The potential curve obtained has been used to determine the Fran&-Condon o\rrlnp of the continuum vibrational levels in the B state with bound levels in the ground ekctronic state.
