Improved Si NMR detection of sterically protected fluorosilanes using the Si(F)-INEPT technique

The ²⁹Si-¹⁹F INEPT NMR method has been applied to significantly reduce the recording time of ²⁹Si NMR spectra of sterically shielded fluorosilanes. This technique furthermore improves the signal to noise ratio to a degree which allows the simultaneous detection of minor byproducts which are below the detection limit using direct acquisition.
