About 1960, it became clear that it was best for me to bring the experimental part of my research program to a close - there was too much to do on the theoretical aspects - and I began the process of winding down the experiments.

Life and career
Marcus was born in Montreal Quebec the son of Esther (Cohen) and Myer Marcus. Marcus’s interest in math would later help him in creating his theory on electron transfer. Marcus made many studies based on the principles that were found within this chemical reaction and through his studies was able to create his famous Marcus theory.

A type of chemical reaction linked to his many studies of electron transfer would be the transfer of an electron between metal ions in different states of oxidation. Rudolph Arthur Marcus (born July 21 1923) is a Canadian-born chemist who received the 1992 Nobel Prize in Chemistry for his theory of electron transfer. Marcus made many studies based on the principles that were found within this chemical reaction and through his studies was able to create his famous Marcus theory.
