The charge shift model has been used to calculate electric field gradients (efg) for various probe-host combinations. The comparison with the corresponding experimental values indicates that the validity of the model depends on sign and magnitude of the charge shift. The model agrees fairly well with experiments for the hosts having positive charge shift. The agreement is good for hosts having negative charge shift only if the magnitude is small (< 0·012).
