A new HMQC-based experiment is presented which allows for an efficient determination of accurate homonuclear coupling-constant values. Pure absorption lineshapes with tilted cross-peak patterns are obtained by a combination of the active-couplingpattern tilting (ACT) scheme with J-scaling. Character

A new constant-time COSY experiment which allows an efficient determination of accurate homonuclear coupling constant values is presented. Characteristic features include an improved scheme for homonuclear active-coupling-pattern tilting (ACT) and an arbitrarily scaled shift and coupling information
Two-dimensional pulse sequences for the determination of hetpeak patterns is also available in two-spin systems. No addieronuclear long-range coupling constants are presented. The setional passive spin is required. Purely absorptive phase in quences are based on the HMQC/HMBC or HSQC technique with
