We measured the dependence of strong non-thermal polarization of cisand trans-azobenzene in a photo-SABRE experiment on the magnetic field. The results are shown in Figures and. The Xaxis corresponds to the strength of the ultra-low field in which photo-SABRE occurs. Both the net magnetization (Iz) and the singlet order (SO) of nuclear spins of azobenzene molecule can be populated at ultralow field in SABRE process by utilizing the singlet order of the parahydrogen. These two spin orders can be separated by selecting the appropriate detection pulse sequence at high field.
