Marshall D. Newton

Senior Chemist Emeritus. Leading figure in the general area of theoretical interpretation of electron transfer (ET) processes. Over four decades, contributed work on the theory of ET, on computations for actual systems, and on understandings of particular theoretical approaches. He extended the palette of ET theory to deal with electrochemical and conductance systems. Analyses of theoretical/computational methods and of their applicability to particular ET structures and behaviors led the community in its efforts to calculate and interpret this crucial, huge class of reactions and processes. His insights, his attention to and understanding of experiment, his focus on the implications of particular formalisms, and his innovative applications of both quantum mechanical and statistical mechanical methods for examining the problems of ET have shaped much of the current understanding about such crucial issues as how ET occurs, how structure/function relationships in ET experiments arise, and how to actually calculate the behaviors of molecular systems undergoing ET processes, from polymers through adlayers, from metal complexes to organics, from interfaces to the gas phase.
