Notes
- Values marked # are not purely derived from experimental data, but at least partly from systematic trends.
- Uncertainties are given in concise form in parentheses after the corresponding last digits. Uncertainty values from Ame2003 denote one standard deviation. Values from IUPAC are expanded uncertainties.
