WEFT - water eliminated fourier transform

From NMR Wiki

This experiment[1] works for molecules whose T₁ relaxation time is shorter than T₁ of water.

In this experiment t_n is selected so that the Z magnetization of water is zero at the moment the 90^o pulse is applied. During the same time Z magnetization of the molecule of interest has a chance to fully relax to equilibrium.
