The 29Si MAS-NMR spectra of kaolinite and metakaolinite are given in Figure 4. The 29Si MAS-NMR spectrum of kaolinite (Figure 4a) displays two well resolved signals at -90.9 and -91.4 ppm attributed ...

The Swedish NMR Centre (SNC) is a National and International infrastructure offering access to one of the best NMR labs in Europe. At present, we offer access to eight different spectrometers, ranging ...

Some of the methods for sensitivity enhancement used in 13C NMR are also applicable to 29Si NMR. Examples include the use of spin-lock polarisation (Figure 6a), and two-dimensional HMBC (Figure 6b) ...

As an example of the scope of an NMR spectrometer, the broadband channel on the X-Pulse can analyse nuclei with Larmor frequencies between 11 - 25 MHz at 1.4 tesla; a few of the nuclei in this range ...
