An experimental value of the spin–spin coupling constant in deuterated molecular hydrogen HD has been obtained, Jpd = (43.112 ± 0.005) Hz (300 K), while investigating two gaseous samples at pressures of 95 and 155 atm. The experimental result does not coincide with Jpd = (43.31 ± 0.05) Hz that was calculated theoretically by Helkager et al. The observed discrepancy ΔJpd ≈ (0.20 ± 0.05 Hz) may point to a manifestation of the involvement of light pseudo-scalar (axion-like) bosons with a mass ma ≈ 1 keV/c2 in the spin–spin coupling of the HD proton and deuteron.
