It is found that supercycled SWf-TPPM-11 and 7 sequences works in a relatively better way for heteronuclear decoupling in isotropic liquids. However these sequences are comparatively lengthy and hence new sequences which are shorter are to be preferred. To achieve this objective, the efficiency of decoupling for the supercycled SWf-TPPM-4 sequence was studied as a function of phase angle. The results are presented in the supporting information.
