✦ Synopsis

A new, edited HMBC experiment is introduced that leads to two subspectra according to the number of protons attached to 13 C nuclei being even or odd, i.e. one subspectrum with C + CH 2 and another with CH + CH 3 . This experiment can be useful for resolving spectral overlap among the typically large number of peaks in HMBC spectra. It is implemented in a broadband version similar to broadband HMBC and demonstrated on prednisolone [(11b)-11,17,21-trihydroxypregna-1,4-diene-3,20-dione].

## Abstract A new improved multiplicity‐edited HMBC experiment is introduced that leads to better __J__ cross‐talk suppression in the even (i.e. C + CH~2~ groups) and odd (i.e. CH + CH~3~ groups) subspectra. By combining data recorded with three different pulse sequences __J__ cross‐talk becomes a

A data processing method, based on double integral calculations, to obtain decoupled highresolution NMR spectra in the weak scalar coupling approximation is described. Data are recorded from conventional spin echo experiments using di †erent values of the delay of the echo. The collected echoes are
