... chose neutral H2 molecules which have two protons each.(In hydrogen atom, the 2000 times larger electron moment overwhelms that of the proton!) The trick was to choose parahydrogen, in which the protons spins are aligned so their moments add up, the electrons in ground state have total spin zero and ...

Electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.
