Description	Schemes for sensitive measurements of spin-spin coupling constants between rare nuclei with low magnetogyric ratios are considered and two combinations of INEPT with gradient versions of (X,Y)HMQC and (X,Y)COSY are suggested as particularly suitable for 29Si,13C couplings. It is demonstrated that the (H,Si)INEPT-(Si,C,Si)gHMQC combination (with 29Si detection) produces excellent results even though it is theoretically inferior to the (H,Si)INEPT-(Si,C)gCOSY combination (with 13C detection.

(en) Byly vyvinuty dvě metody na měření zmíněných konstant. Obě využívaji přenos polarizace metodou INEPT a dále jsou založeny na pulsních sekvencích (X,Y)HMQC a (X,Y)COSY. Využití obou metod je demosntrováno na praktickém příkladu. (cs)
