Notes:
The absorption, magnetic circular dichroism (MCD), and magnetic linear dichoism (MLD) spectra of Ni atoms isolated in an argon matrix (4.2 K) have been measured. By utilizing the complementarity of the predicted MCD and MLD signals for transitions to states of different J values, together with the known gas phase positions and relative intensities, an assignment for all observed bands has been made. Most bands in the region 360–270 nm originate from atoms in sites whose ground state is 3D3, whereas bands in the ∼240–230 nm region arise from atoms whose matrix ground state is 3F4. Thermal annealing results in the disappearance of the 3F4 ground state atoms, but not the 3D3 ground state ones.
