Publication of a translation into another language is subject to the additional condition of prior approval from the relevant IUPAC National Adhering Organization. Reporting of stable hydrogen, carbon, and oxygen isotopic abundances (Technical Report) Abstract-To eliminate possible confusion in the reporting of isotopic abundances on non-corresponding scales, the Commission on Atomic Weights and Isoto ic Abundances recommended at the 37 * General Assembly at Lisbon, Portugal that (i) 'H / H relative ratios of all substances be expressed relative to VSMOW (Vienna Standard Mean Ocean Water) on a scale such that 2H/'H of SLAP (Standard Light Antarctic Precipitation) is 0.572 times that of VSMOW, (ii) 13C/'2C relative ratios of all substances be expressed relative to VPDB (Vienna Peedee belemnite) on a scale such that 13C/12C of NBS 19 carbonate is 1.00195 times that of VPDB, and (iii) l8O/l6O ratios of all substances be expressed relative to either VSMOW or VPDB on scales such that 180/160 of SLAP is 0.9445 times that of VSMOW. |
