Symmetry considerations were used in presenting a model of the electronic structure and the associated dynamics of the N-vacancy center in diamond. The model accounts for the occurrence of optically induced spin polarization, for the change of emission level with spin polarization and for new experimental measurements of transient emission. The rate constants given were in variance to those reported previously.
