Crystal field calculations of oscillator strengths are performed for some models of point‐charge coordination around Nd 3+ in glass. The results are compared with the experimental values on silicate and borate glass (crystal field symmetry C 3c , D 3h respectively). A model in which Nd 3+ has seven oxygen neighbours (resembling the A structure of crystalline Nd 2 O 3 ) and a model in which it has nine oxygen neighbours (as in neodymium ethylsulphate), give best agreement with experiments on silicates, and borates, respectively.
