But there was still considerable opposition.

Robinson was a Nobel laureate, and many chemists were reluctant to accept a theory of chemical reactions so thoroughly derived from physics and quantum mechanics. Did the new theory account for an experimentally verified, regularity of chemical reactions known as the Hammett rule? There he met Roald Hoffmann, with whom he would later share the Nobel Prize.

Woodward published, inwhat came to be called the Woodward-Hoffmann Rule. Their observations linked experimental results with the phenomenon of orbitals, highlighting the importance of orbital symmetry control in chemical reactions. In Fukui spent six months as a visiting scholar at the Illinois Institute of Technology in Chicago with support from the U.

National Science Foundation. During this period he wrote two major papers on chemical reaction theory. One dealt with the concept of orbital symmetry control developed by Hoffmann and Woodward as a way to demonstrate the greater breadth of the frontier orbitals theory as compared to the older electronic theory. His other paper applied perturbation theory to some original qualitative notions, showing that as perturbations distort the HOMO of one reactant and the LUMO of the other, they affect the energetics of various reaction pathways.

By lecturing during this period at a number of American research universities while visiting corporate laboratories, Fukui gradually became better known in the United States. In he was named a member of the National Academy of Sciences. On 9 January Fukui died in Kyoto of peritoneal cancer, survived by his wife Tomoe Horie Fukui, whom he married inand their two grown children.

His use of advanced mathematics made his theories difficult for most chemists to understand, and his articles were published in journals that were not widely read in the United States and Europe. In an interview quoted in the New York Times, Fukui also attributed some of his obscurity to resistance from Japanese colleagues: "The Japanese are very conservative when it comes to new theory.

But once you get appreciated in the United States or Europe, then after that the appreciation spreads back to Japan. Woodward of Harvard, and in they came to conclusions that were similar to his, though they had arrived there along a different path. Staying away from complex math, these two developed a formula almost as simple as a pictorial representation.

Taken together, the work of Fukui and the American team enabled research scientists to predict how reactions would occur and to understand many complexities never before explained. These formulae answered questions about why some reactions between molecules occurred quickly and others slowly, as well as why certain molecules reacted better with some molecules than with others.

They removed much of guesswork from this area of chemistry research. For the advancements in knowledge their work had brought, Fukui and Hoffmann were jointly awarded the Nobel Prize in chemistry. Woodward, who would probably also have shared in the prize, had died two years before. In fact, later on when teaching he would recommend experimental thesis projects for his students to balance them out, theoretical science came more natural to students, but by suggesting or assigning experimental projects his students could understand the concept of both, as all scientist should.

Inhe was appointed a lecturer in fuel chemistry at Kyoto Imperial University and began his career as an experimental organic chemist. InFukui with his young collaborators T. Yonezawa and H. Shingu presented his molecular orbital theory of reactivity in aromatic hydrocarbonswhich appeared in the Journal of Chemical Physics. At that time, his concept failed to garner adequate attention among chemists.

Fukui observed in his Nobel lecture in that his original paper 'received a number of controversial comments. This was in a sense understandable, because for lack of my experiential ability, the theoretical foundation for this conspicuous result was obscure or rather improperly given. His interests centered on submolecular phenomena in industrial chemical processes and their mathematical descriptions.

His major breakthrough came in the early s when he proposed the concept of frontier orbitals. He discovered that only a small number of molecular orbitals, which he named frontier orbitals, significantly influenced reaction pathways. This concept states that a chemical reaction occurs when the highest occupied molecular orbital HOMO of one molecule interacts with the lowest unoccupied molecular orbital LUMO of another.

Symmetry Principles and Nobel Prize Further developing this theory, Fukui realized that the geometric arrangement symmetry of frontier orbitals played a crucial role in chemical reactions.
