Line Plot from Scientific Research

Representative single-scan 1H NMR spectra recorded at 243 K after addition of parahydrogen to an equilibrium mixture of 1 and 2A in methanol-d4. The spectra are recorded (upper to lower) ca 2 min, 20 min, 45 min, and a few hours after parahydrogen addition at 243 K. The lower spectrum is recorded at 298 K after the sample was warmed to room temperature and left for 2 days. Signals denoted as M correspond to a methanol or water-bound complex.
