By detecting the nuclear free precession signals in rapidly switchable external magnetic fields, we retrieve the three-dimensional spatial coordinates of the nuclear spins with sub-Angstrom resolution and for distances beyond 10 Angstroms. We further show that the Fermi contact contribution can be constrained by measuring the nuclear g-factor enhancement. The presented method will be useful for mapping the atomic-scale structure of single molecules","authors_text":"C. L. Degen, J. M. Boss, J. Zopes, K. M. Itoh, K. Sasaki, K. S.
