Figure 4: 13C polarization of SUC polarized with ECHO (squares) as a function of the hydrogenation duration thydr and fit (line).

Figure 4:

FUM (5 mM) was hydrogenated at 90° C and 20 bar pH2 pressure for different durations (thydr) before ECHO (tE = 70.0 ms) was applied and the polarization was measured (SUC.E1). A function was fitted to the data to extract the hydrogenation and relaxation constant tcat and tspin (Equation 8).
