Outline of Final Research Achievements

The natural stable isotopic abundances of bio elements from hydrogen to sulphur have been used for tracing the material cycles. In this project we have invented the measurement methodology of isotopomers, a molecular species with numerous isotopic molecules composed of various modes of isotopic substitution, and explored the analysis of those enormous data.
They are applied to the global warming related environmental materials and bio molecules, their precursors, as well to describe their origins, production and/or consumption processes quantitatively.
Some isotopomers unknown and short-life intermediates which cannot be observed have been studied by the ab-initio theoretical calculation, checked by the experiments and subject to models described below. The 3 dimensional chemical transfer global circulation model has been applied for the nitrogen oxides and sulphur oxides, and the cycles of a greenhouse gas and aerosols have been well analyzed with their isotopomer data.
