Silicon29
Silicon-29 is a stable isotope of the element silicon, which has an atomic number of 14 and a mass number of 29. In nature, it accounts for about 4.7% of silicon, with the majority being 28Si (~92%) and a smaller portion of 30Si (~3%). Unlike 28Si, 29Si contains a nonzero nuclear spin and is therefore observable by nuclear magnetic resonance (NMR) techniques. Its presence is important in fields ranging from chemistry to materials science.
Nuclear properties of 29Si include a spin of 1/2 and a corresponding magnetic moment. The gyromagnetic ratio
Applications and use in research involve 29Si NMR spectroscopy to probe silicon-containing compounds, networks of silicon-oxygen
Availability and safety: 29Si is a stable, non-radioactive isotope of silicon. It is commercially available in
