The relaxation time of liquid 129 Xe is very long (>15 min) and the signal at thermal equilibrium is weak. Therefore, determination of the absolute polarization enhancement of hyperpolarized 129 Xe by direct measurement is tedious. We demonstrate a fast and precise alternative, based on the dipolar
