Norrish was largely responsible for the advance of reaction kinetics to a distinct discipline within physical chemistry.
Norrish was born and educated in Cambridge and spent his academic career there, becoming professor in 1937.
By varying the time delay between two flashes, Norrish was able to study the kinetics of the formation and decay of very short-lived radicals or ions.

Norrish did his undergraduate and doctoral work at the University of Cambridge, served as research fellow at Emmanuel College, Cambridge, and directed the university's physical chemistry department for 28 years.
Norrish and Porter, who worked together between 1949 and 1965, used the new technique of flash photolysis to study the intermediate stages involved in extremely rapid chemical reactions.
Norrish became a professor emeritus in 1963, though he continued to work with individual students and as an industrial consultant.

Ronald George Wreyford Norrish was born in 1897, in Cambridge, England.
It was Norrish who coined the term 'gel effect' to describe the final slowing-down stages of polymerization as a solution undergoing the process becomes increasingly semi-fluid or viscous.
Norrish and Porter continued their research together from 1949 to 1965, perfecting their technique to allow analysis of short-lived intermediate compounds down to a thousandth of a millionth of a second.

 In a flash, he saw substances' brief lives - smh.com.au
It was for his work on techniques for observing and studying extremely fast chemical reactions during the processes of combustion, explosion and chain reaction that, with fellow Cambridge scientist Ronald Norrish, and with Manfred Eigen, of Gottingen, he shared the Nobel Prize for Chemistry in 1967.
When Porter had joined Professor Norrish at Cambridge after the war, Norrish was trying to study the fragments of molecules made when certain chemicals are exposed to intense beams of light.
While Porter's early work with Norrish involved gases, he later developed methods to apply flash photolysis to liquids and solutions, enabling it to be used in organic chemistry, biochemistry and photobiology.

English chemist, corecipient with fellow Englishman Ronald George Wreyford Norrish and Manfred Eigen of West Germany of the 1967 Nobel Prize for Chemistry.
All three were honoured for their studies in flash photolysis, a technique for observing the intermediate stages of very fast chemical reactions.
In this technique, a gas or liquid in equilibrium is illuminated with an ultra-short burst of light that causes photochemical reactions in the substance.

Norrish was born in Cambridge and educated at the Perse School, 1908-1915, and Emmanuel College, Cambridge where he read for the Natural Sciences Tripos, 1919-1921, specialising in chemistry for Part II.
It consists of correspondence received by Dainton and Thrush while they were working on the Royal Society memoir of Norrish, a few school and undergraduate diaries and notebooks, and some rather miscellaneous notes, drafts and correspondence.
Norrish's school chemistry set is in the Science Museum, London.

 EducationGuardian.co.uk | Special Reports | Obituary: Lord Porter of Luddenham
His involvement with physics and with short-wave propagation and reflection were to prove crucial to the later development of his career.
In 1945, he went to Cambridge University as a post-graduate research student with Professor Ronald Norrish, and began studies of the very elusive short-lived intermediaries (free radicals) in photochemical reactions.
These disappear, as it were, almost as they are born, yet if they could be visualised step by step, they would reveal the route by which the reaction took place.

The importance of this work was recognised in 1967 by the award of the Nobel Prize for Chemistry, jointly with Norrish and Manfred Eigen of Germany.
In 1955 George Porter returned to his native county as Professor of Physical Chemistry at Sheffield, where he gathered together a group of scientists who turned the department into one of the best in the country.

Porter and Norrish found this technique useful for measuring chemical reactions with a duration of several thousandths of a second, but it was not fast enough for the study of reactions involving the production of unstable, highly reactive free radicals (atoms or molecules with at least one unpaired electron).
By varying the time between the two flashes, Porter and Norrish were able to determine the course of chemical reactions that occur in millionths of a second.
There, in collaboration with Norrish, he continued to study the behaviour of free radicals and fast chemical reactions.

Professor Zewal’s achievement of being able to investigate chemical reactions on the time-scale that they occur is the latest development in a series by previous Nobel Prize winners leading to the understanding of chemical reactions and their observations on decreasing time-scales.
Ronald Norrish and George Porter, Nobel Laureates in Chemistry 1967, achieved time resolution in the millisecond to microsecond range by using a flash lamp.
They shared the prize with Manfred Eigen, who reached a similar time resolution by exposing his chemical solution to a pressure or electrical shock or a heat shock.

One of the most highly regarded and well-known scientists in Britain, and a Nobel prize-winner, he had a gift for communicating his enthusiasm for science.
It was for his work on techniques for observing and studying extremely fast chemical reactions during the processes of combustion, explosion and chain reaction that, with his Cambridge colleague Professor Ronald Norrish, and with the German scholar Manfred Eigen, he shared the Nobel Prize for Chemistry in 1967.
Porter and Norrish developed flash photolysis, using pulses of light even shorter than the reactions they sought to study, to open up a window onto a hitherto impenetrable world.

At the age of 18, she began studies at Newham College, a women's college in Cambridge, and graduated in 1941.
The following year she worked with Ronald Norrish, a physical chemist who would later win the Nobel Prize in Chemistry in 1967.
From 1942 to 1946, Franklin worked for the British Coal Utilization Research Association, where she discovered the structural changes that occur when coals and charcoals are heated, thus explaining why some carbons form graphite under these conditions.
