Description
The Commission on Isotopic Abundances and Atomic Weights (CIAAW) is an international scientific committee of IUPAC under its Inorganic Chemistry Division. Since 1899, CIAAW is entrusted with periodic critical evaluation of atomic weights of elements and other cognate data, such as the isotopic composition of elements. CIAAW has been a part of IUPAC since the first General Assembly of IUPAC in 1920. Visit the Commission’s website ciaaw.org for more information.
