(a) Pre-SAT180, a pulse sequence to effectively suppress the faraway water signal. (b) A schematic diagram shows the faraway water region and how its suppression is achieved. Arrows after each pulse indicate the contribution to the transverse magnetization from the different portions of the sample, including bulk solvent, faraway water and the solute. Top and bottom portions of the figure indicate inversion pulse on or off conditions. Receiver phase shifting creates the difference spectrum with improved solvent suppression [reproduced with permission from Ref. [38]].
