Abstract
The signs of the directly bonded spin–spin couplings J(13C–1H) and J(29Si–1H) are shown to be opposite in methyldichlorosilane and it is concluded that the reduced coupling constant between directly bound Si and H is always positive. The signs and magnitudes of all six coupling constants in 13CH3 29SiHCl2 are determined by tickling procedures.Keywords
