Abstract We deduce new expressions for g-factors of the 3d9 ions with a compressional tetragonal symmetry, in which we consider not only the contribution from the spin-orbit coupling of the central transition metal ion but also that of the ligand orbits as well as the admixture of 2B1g into 2A1g (ground state). By using the new formulae, the electron paramagnetic resonance g-factors for NaCl:Ni+(I) are studied. Thus, the puzzle that the g‖-shift is positive is reasonably explained.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
