In 2012 Lange et al. suggested a distinct bonding mechanism: perpendicular paramagnetic bonding, generated by the stabilization of antibonding orbitals in their perpendicular orientation relative to an external magnetic field. The perpendicular paramagnetic bonding explains the bonding of H2 in the 3Σu+(1σg1σu*) triplet state and of He2 in the 1Σg+(1σg21σu*2) singlet state, as well as their preferred perpendicular orientation in the external field. In this paper, the culture of quantum chemistry and life in Norway are also briefly touched upon.
