Figure 5
1H (a) and 1H13C CP MAS NMR (b) spectra of 15 mM spin labeled eptifibatide 3 in a glycerol-d8/D2O/H2O matrix with (MW on) and without (MW off) microwave irradiation measured at 9.4 Tesla at 8 kHz spinning rate. In the 13C spectra the two signals at 60.7 ppm and 70.5 ppm refer to the glycerol and the small signal at 0 ppm is attributed to the silicon plug marked with #, used to tightly close the liquid in the NMR rotor. The asterisks indicate the spinning side bands of the glycerol in the 13C spectra and the spinning sidebands of the water in the 1H spectra.
