A robust, sensitive, and versatile HMBC experiment for rapid structure elucidation by NMR: IMPACT-HMBC.
A robust, versatile and easy to optimize HMBC experiment for complex organic structure elucidation which has been experimentally tested on cholesteryl acetate, cyclosporine and isopropylidene glycerol is described. The proposed experiment, IMPACT-HMBC (improved and accelerated constant-time heteronuclear multiple-bond correlation), combines sensitivity, easy experimental setup and can be recorded with short recovery times.
