The nuclear magnetic resonance (NMR) line shifts of ortho‐hydrogen molecules relative to the lines of hydrogen deuteride (HD) molecules in a para‐hydrogen matrix are reviewed in terms of the molecular spectroscopy of the rotational energy levels of ortho‐hydrogen molecules in high magnetic fields. This example is used to illustrate how known molecular spectra can be used to determine fundamental interactions in condensed matter, and how similar methods could be used to measure the magnetic fields near astrophysical objects such as white dwarfs and neutron stars. © 1997 John Wiley & Sons, Inc.
