摘要：
The optical absorption spectrum of NiO is measured at low temperatures and energies between 7000 and 30 000 cm-1. An assignment to cubic crystal field components of the 3d8 configuration of Ni2+ is proposed. The fine structure of the A band, showing two sharp lines at the lowest energies, 7811 and 7852 cm-1, is explained by additional spin-orbit interaction, rhombohedral exchange striction and an orthorhombic transverse molecular field due to antiferromagnetic long-range order.
