Readout sequence to boost the SNR of the C7 spectrum. It transforms the 1H spins from Z to identity and thus enables the decoupling of 1H channel. The phase correction compensates for the chemical shift evolutions, after which all relevant spins are along the y-axis. In principle, this technique improves the SNR by a factor of 32, and makes the measurement of f or g practical using one scan
