JIANG YUANSHENG

Jiang Yuansheng, born in 1931, is from Yichun, Jiangxi Province. He was graduated from Department of Chemistry, Wuhan University in 1953 and from Jilin University as a graduate majoring in physical chemistry in 1956. He was promoted to be a professor in 1978. He has worked as a professor of Department of Chemistry, Nanjing University since 1992. He was elected the academician of the Chinese Academy of Sciences in 1991 and is a member of the 6th CPPCC, 1983-1986. He has been a member of the Board of Directors of Chinese Chemical Society (CCS), 1978-1989, and a member of standing Committee of CCS, 1990-1994. Jiang is also the member of several Chinese chemical journals and the member of international advisory board of J. Theor. and Comput.Chem. and Phys.Chem.Chem.Phys.(PCCP). He is the academic member of The International Academy of Mathematical Chemistry.
He has engaged in research and education of theoretical and computational chemistry for a long time. Since 1960, he published the macromolecular solgel formula to demonstrate the crosslinking degree and carried out the study of Ligand Field Theory, solved the problem of calculating the coupling coefficients and the spinorbit interaction of point group symmetry. Inthe middle of 1970s, Prof. Jiang devoted himself to chemical graph theory and applications. He summarized the fundamental ideas of the simple molecular orbital theory into three theorems. Then he proposed the graph contraction method and worked out analytical results of graph invariants to rationalize the relationship between properties and structures of conjugated hydrocarbons. He advanced a fiveparameter formula for interpreting the aromaticity of molecules in agreement with the experiments. These achievements are often called “The Chinese School of Chemical Graph Theory” and “JiangTangHoffmann Scheme” in the literature. Overall in 1990s, he studied the classical valence bond (VB) theory, focusing in calculating the exact energy levels and wave functions of medium and large molecules. These original VB results have been used in validation and calibration for other approximate VB treatments. One of his review articles has been published in the monograph Valence Bond Theory (D.J.Cooper, editor, ELSEVIER, 2002). Another one will appear in Advances in Quantum Chemistry (D.J.Klein, editor, Academic). Pref. Jiang was awarded the Science Conference Prize in 1978, the firstclass Prize for National Natural Science in 1982 and 1987, the firstclass Prize for Scientific and Technological Progress (STP) of Ministry of Education in 1999, and the Prize for STP of Ho Leung Ho Lee Foundation in 2005.
