A simple pulse sequence in inverse-detection mode is proposed for the detection of heteronuclear long-range couplings. In the resulting 2D heteronuclear multiple-bond correlation (HMBC) spectra, pure-absorptive peak patterns are obtained along both frequency dimensions. Since the heteronuclear coupl

## Abstract An efficient pulse sequence for measuring long‐range CH coupling constants (__J__~CH~) named selective __J__‐resolved HMBC has been developed by replacing a ^1^H 180° pulse with a selective ^1^H 180° pulse and the HMBC pulse scheme with the constant time (CT) HMBC employed in the __J_

## Abstract A modified version of CPMG‐HSQMBC pulse scheme is presented for the measurement of long‐range heteronuclear coupling constants. The method implements adiabatic inversion and refocusing pulses on the heteronucleus. Low‐power composite 180° XY‐16 CPMG pulse train is applied on both proton

A new technique is described which enables accurate values of heteronuclear long-range coupling constants to be obtained from highly distorted multiplets in two-dimensional correlation spectra. The technique uses a simple data fitting of the distorted multiplet with a model obtained from the convent
