In experiments, C1, C2, C3 and C4 form a 4-qubit quantum processor. In this table, the chemical shifts with respect to the Larmor frequency 150 MHz and J-couplings (in Hz) are given as the diagonal and off-diagonal elements, respectively. The methyl group M, H1 and H2 were decoupled throughout all experiments.
