Nitrogen fixation. The two aspects of the nitrogen cycle having the greatest impact on the biological pump are nitrogen fixation and denitrification. The first provides a mechanism for drawing on the extensive atmospheric pool of N2 gas in support of primary production. The second provides a pathway for DIN to be converted back to N2 gas and removed from the ocean system. 

N2 Complexing. LCAO-MO calculations have been made on the electronic structures of the complexes M,N2 (M = H, Li, Be, or B" ), N2,BX3 (X = F or H), and M,N2M (M = H, Li", B", or BH3). The calculations were used to discuss models of nitrogen fixation by enzymes in biological systems. Quantum mechanical calculations by the CNDQ/2 method confirm the possibility of N2 complex formation with Li and F" ions. The contribution of covalent bonds to the energy of the complexes has been analysed and their lability discussed. ... 

This paper demonstrates the development and use of models in two areas of bioinorganic chemistry, the mechanism of biological nitrogen fixation and the enzymatic function of vitamin B12 coenzymes.
