Nuclear spin coupling crossover in dense molecular hydrogen

Solid hydrogen has increasingly hindered rotation under high pressure, but the effect on spin isomer populations had not been directly probed. Here the authors measure NMR spectra of solid hydrogen up to the megabar, and observe the crossover to a spin 1/2 dipolar system above 70 GPa where distincti...

description	Solid hydrogen has increasingly hindered rotation under high pressure, but the effect on spin isomer populations had not been directly probed. Here the authors measure NMR spectra of solid hydrogen up to the megabar, and observe the crossover to a spin 1/2 dipolar system above 70 GPa where distinction between ortho and para spin isomers is lost.
