Biography

Jiang Yuansheng, male, Han nationality, is a native of Yichun, Jiangxi Province. He studied chemistry at Wuhan University and Jilin University.

Jiang graduated from Jilin University in 1956 and became a professor at Nanjing University. He is best known for his discoveries in the field of molecular theory. In the 1960s, Jiang published his Cross-Linking Macromolecule Gelatin Formula, which demonstrates the cross linking degree with the gelatin amount. In the 1970s, he completed the ligand field theory by addressing several unclear points relating to point cluster coefficients. His achievements on the graphical molecular orbital theory and its application include: formation of a "Three-Theorem" Huckel theory; proposal of a graphical shrinkage method and a large number of original results on the calculation and simplification of molecular graph constants as well as their relationship; and proposal of a five-parameter formula that developed the aromaticity theory.

Jiang developed a theoretical explanation on the aberration of tri-nucleus molybdenum clusters, a field of atom clusters and solid state research. He is the principal author of two theoretical chemistry works: "Theory and Methods of Ligand Field" and "Graphical Molecular Orbital Theory". Jiang Yuansheng was elected an academician of the Chinese Academy of Sciences in 1991.
