A pulse sequence for obtaining 13C-lH shift-correlated spectra with full 'H-'H decoupling b described and evaluated. It is concluded that the sequence provides excellent resolution, even for strongly coupled methylene group The sensitivity is superior to those of existing sequences based on "C detec

Selective polarization transfer from proton to adjacent carbon was accomplished by either selective crosspolarization or selective refocused-INEPT. Magnetization was transferred in the subsequent step to remote carbons separated by one, two or three bonds. The acquired data were processed by a new s
## Abstract Twoβdimensional ^1^Hβdetected {^1^H, ^13^C} shift correlation spectra of oligosaccharides usually suffer from low resolution in the ^13^C frequency domain. This drawback can be overcome through a simple modification of the HSQC experiment, namely by implementing a selective ^13^C 180Β° p
Accordion excitation provides the means of sampling a broad range of potential long-range heteronuclear couplings in a single experiment. Two long-range heteronuclear experiments, ACCORD-HMBC and IMPEACH-MBC, have been developed thus far that offer accordion excitation. The results obtained with the
## Abstract The performance of the SELINCOR sequence is greatly enhanced by using pulsed field gradients. It is shown that with this sequence, a ^13^Cβresolved COSY can be performed on a selected proton of an attached carbon atom. This experiment enables one to detect and evaluate COSY cross peaks
