Method for detg. the coupling const. between two spins using a suitably chosen pair of selective expts., soft-COSY on the one hand and pure in-pause correlation spectroscopy (PICST) on the other, is presented. In weakly coupled system, soft-COSY yields cross-peak multiplets with structures that are analogous to what can be obtained with small-flip-angle COSY or E.COSY. [on SciFinder (R)]
