We note that multiple coupling multiplicities cannot be decoupled simultaneously using NUWS-NUS, unlike CT experiments, as separate sampling schedules are required for each pattern of scalar coupling evolution. However, because these different types of spin systems are generally in well separated regions of the spectrum, and analyses often focus on only one subgroup of signals, such as methyl groups (excluding methionine Cε, which do not have 1 J CC couplings), in practical situations this requirement may not be overly restrictive. Moreover, as acquisition is rapid relative to insensitive CT-HSQC experiments, multiple sampling schemes may be acquired in separate experiments if required.
