Indirect nuclear spin–spin coupling constants of nitrogen-15 to silicon-29 in silylamines
Abstract
The 15N–29Si spin–spin coupling constants in silylamines have been measured from 29Si satellites in their natural abundance 15N n.m.r. spectra in an INEPT sequence for accumulation of signals and interpreted in terms of Fermi-contact interaction; the sensitivity of 1J(15N–29Si) to dπ–pπ bonding was noted.
