Notes:
Limited resolution in indirect detected frequency dimensions (evolution periods) in multi-dimensional spectroscopy is a common problem, especially in the carbon dimension of heteronuclear experiments. Folding of signals in empty regions can overcome these problems. To record the spectra in a pure phase certain conditions have to be fulfilled to account for unavoidable deviations from zero time of the zero increment. A new slight variation of inverse heteronuclear correlation pulse sequences is proposed to allow pure phase spectra. Practical applications are given.
