Quantum wavepacket dynamics on the BH 1 Sigma + states

We investigate the dynamics of the ground state and the first three singlet 1 Sigma + excited states of BH using the split-operator method. Ab initio calculations show that these states have strong non-adiabatic couplings, resulting in a complex topology of avoided crossing regions and double well potentials. We attempt to find a method to populate the second minimum of B 1 Sigma +, enabling experimental observation of its vibrational states.
