American Chemical Society

“for his pioneering work combining theoretical chemistry and digital computation to further our fundamental understanding of chemical reactivity and molecular interactions through visionary accomplishments in the areas of potential energy functions, accurate quantum dynamics, variational transition state theory, and the use of electronic structure theory for calculations of reaction rates and solvation effects "

American Chemical Society

“for fundamental contributions to the theory of chemical reaction dynamics, especially quantum mechanical scattering theory and variational transition state theory”

American Chemical Society

“For creative contributions to theoretical chemistry, in electronic structure, chemical dynamics, continuum solvation, and the development of new density functionals for practical calculations of thermochemical quantities.”
