    • In Gaussian, these calculations are simply invoked by the NMR=GIAO or NMR=CSGT keyword, respectively. The isotropic chemical shieldings in ppm appear in the output for each atom in the section labelled "Magnetic shielding (ppm)". They are followed by the complete shielding tensors and their eigenvalues which can, however, be ignored for the present purposes
