An experiment that excites exclusively coupled nuclei pairsis presented. It involves the biselective defocusing and refocusing of coupled transverse magnetization under double pulsed field gradient spin echo conditions. Application to the extraction of subspectra from crowded COSY spectra is present
Variants of the HSQC and HMBC experiments are described. They allow the restriction of the heteronuclear chemical shift domain without causing spectral folding. Selectivity is introduced in the HSQC experiment by means of excitation sculpting. The selective element of the pulse sequence is a double

A band-selective homonuclear decoupled TOCSY sequence is described and compared with the standard TOCSY experiment, using a sample of a DNA 15mer. Band selection and homonuclear decoupling (BASHD) was achieved along the evolution dimension using a band-selective double pulse Γeld gradient spin echo
