Three-dimensional MEIOSIS pulse sequence for simultaneous acquisition of three 3D spectra: NCACX, NCOCX, and CAN(CO)CX. The phase cycle is given by ϕ1 = (y, −y)2, ϕ2 = x, x, −x, −x, and ϕrec = x, −x, −x, x. Sates mode acquisition of indirect dimensions is obtained by alternating ϕ2, and ϕ* phases between x and y.
