Calculation was made here of the sodium and nitrogen nqcc tensors in NaNH2NaNH2NaNH2NaNH2NaNH2 on the ro structure of Burton et al. [1].  These calculated nqcc's are given in Table 1, along with the experimental Xaa for 23Na.  Structure parameters are given in Table 2.


 








In Table 1, the subscripts a,b,c refer to the principal axes of the inertia tensor.  RSD is the calibration residual standard deviation for the model for calculation of the nqcc's.
