Professor Emeritus

James Tyrrell

B.Sc.(Hons), University of Glasgow, 1960
Ph.D., University of Glasgow, 1963
Postdoctoral Fellow, McMaster University, 1963-65
Postdoctoral Fellow, National Research Council,Ottawa,Canada, 1965-67

The focus of my research is the application of quantum mechanical, molecular orbital methods to the determination of molecular structure, fundamental vibrations, and other molecular properties. Projects include the determination of transition state structures and frequencies for reactions thought to be important in atmospheric chemistry and of reactions of potential value for the storage and release of hydrogen
