description George Porter Overview

George Porter (1922-2019) was a British physical chemist renowned for his development of flash photolysis. This technique revolutionized the study of reaction kinetics and photochemistry by allowing researchers to directly observe extremely fast chemical processes. His work significantly advanced understanding in areas like atmospheric chemistry and polymer science. Primarily utilized by chemists and physicists investigating rapid reactions, Porter’s methods remain fundamental within these fields.

help George Porter FAQ

When did George Porter win the Nobel Prize in Chemistry?

George Porter shared the 1967 Nobel Prize in Chemistry with Ronald Norrish and Manfred Eigen. The award recognized work on extremely fast chemical reactions, including flash photolysis.

What is flash photolysis in Porter's work?

Flash photolysis uses a short burst of light to start a reaction and then studies the short-lived intermediates that appear. Porter and Norrish developed the technique after World War II, making chemical events in microseconds easier to observe.

Was George Porter connected to the Royal Institution?

Yes, Porter became director of the Royal Institution in London in 1966. He later became a major public advocate for science in Britain, including through the public understanding of science movement.

What fields use techniques descended from Porter's work?

Flash photolysis and related pump-probe methods are used in physical chemistry, photochemistry, biology, and materials science. Modern versions often use lasers with nanosecond, picosecond, or femtosecond pulses.
