Deuteron and triton magnetic moments from NMR spectra of the hydrogen molecule

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.
