Robert J. Le Roy (September 30, 1943 – August 10, 2018) was one of Canada's leading chemists who held the distinguished title of "University Professor" at the University of Waterloo.


His work on the Morse/Long-range potential with his former student Nike Dattani of Oxford University was referred to as a "landmark in diatomic spectral analysis" in.[1] In the landmark work, the C3 value for atomic lithium was determined to a higher-precision than any atom's previously measured oscillator strength, by an order of magnitude. This lithium oscillator strength is related to the radiative lifetime of atomic lithium and is used as a benchmark for atomic clocks and measurements of fundamental constants.[2]
