Notes

I am grateful to Professor Robin Harris (University of Durham, UK) who provided much of the NMR data, which are copyright 1996 IUPAC, adapted from his contribution contained within reference 1. Where given, data for certain radioactive nuclei are from reference 2. I am also grateful to Professor Pekka Pyykkö (University of Helsinki, Finland) who provided the nuclear quadrupole moment data (references 3 - 5). The isotopic abundances are taken from the naturally occurring isotopes section within WebElements.
