The NMR spectroscopy determines the physical and chem… The NMR behaviour of 1 H and 13 C nuclei has been exploited by organic chemist since they provide valuable information that can be used to deduce the structure of organic compounds. They all yield narrow signals over a very wide chemical shift range. 4. 119Sn is very slightly more sensitive than 117Sn, so 119Sn is therefore usually the preferred nucleus.
