Effect of deuteration on T1-relaxation rates and enhancements Ɛ of 15N2-diazirine 2. A) Negligible effect of deuteration of diazirines 2 on T1-relaxation rates at 1 T (within the experimental error). B) T1-relaxation rate for 15N polarization of d0−2 and d5-2 as a function of the magnetic field. SABRE-SHEATH conditions: diazirine d0-2, 2, or d5-2 (12.5 mm) in [D4]MeOH, Ir precatalyst B (125 μm), and pyridine (1.00 mm).
