This simple idea served to provide information on the geometrical shape of reacting molecules, and I was able to make the role of the frontier orbitals in chemical reactions more distinct through visualization, by drawing their diagrams.

Fukui observed in his Nobel lecture in 1981 that his original paper 'received a number of controversial comments. Work

He was professor of physical chemistry at Kyoto University from 1951 to 1982 president of the Kyoto Institute of Technology between 1982 and 1988 and a member of the International Academy of Quantum Molecular Science and honorary member of the International Academy of Science. " In another interview with The Chemical Intelligencer he further elaborates on his criticism by saying "As is known worldwide Japan has tried to catch up with the western countries since the beginning of this century by importing science from them.

His prize-winning work focused on the role of frontier orbitals in chemical reactions: specifically that molecules share loosely bonded electrons which occupy the frontier orbitals that is the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO). Kenichi Fukui was co-recipient of the Nobel Prize in Chemistry in 1981 with Roald Hoffmann for their independent investigations into the mechanisms of chemical reactions. Kenichi Fukui (福井 謙一 Fukui Ken'ichi October 4 1918 – January 9 1998) was a Japanese chemist.
