Good agreement with accepted values.

Enhanced understanding of nuclear magnetic shielding effects.

Abstract

We present a theory and calculations of the nuclear magnetic shielding with finite nuclear mass effects and determine magnetic moments of deuteron and triton using the known NMR spectra of HD and HT molecules. The results $\mu_d = 0.857\,438\,234\,6(53)\;\mu_N$ and $\mu_t = 2.978\,962\,471(10)\;\mu_N$ are more accurate and in a good agreement with the currently accepted values.
