## Abstract The gradient pulse sequences for measurement of small long‐range couplings between heteronuclei (^29^Si^13^C) in natural abundance reported to date (INEPT‐(Si,C)gCOSY and INEPT‐(Si,C,Si)HMQC) suffer from significant signal loss when these nuclei (^29^Si, ^13^C) are coupled through one‐
