In 1946, Frank Libby of the Institute of Nuclear Sciences in Chicago initiated the dating of carbon-based artifacts by analysing the extent of radioactive decay. 

Alan MacDiarmid (1927-2007) once said "Chemistry is about people" In this spirit, full names and birth and death dates are given to all the scientists quoted in this book such brief historical data may help illuminate how and when science was done. I have resisted mentioning who was a Nobel prize winner too many to list, and some worthy scientists—for example, Mendeleyeff, Eyring, Edison, Slater, and Tesla—were not honored. I owe a deep debt of gratitude to many people who have educated me over several decades, as live teachers and silent authors. In particular, I am indebted to Professor Willard Frank Libby (1908-1980), who taught us undergraduates at UCLA to love current research problems and led us into quite a few wild-goose chases Professor Harden Marsden McConnell (1927- ), who led us at Caltech and Stanford by example to see what are... 

Radiometric dating As radioisotopes have a given half-life they can be used to calculate or date a sample. Referred to as radiometric dating (including carbon dating), it is possible on the basis of a measure of half-life of an isotope in a sample to determine its age or how long it has existed. Radiocarbon dating was discovered in 1949 by the American chemist, Willard Frank Libby, who was awarded the Nobel Prize in Chemistry in 1960 /or his method to use carbon-14 for age determination . 

Libby, Willard Frank (1908-1980) American Physical chemist Willard Frank Libby was born in Grand Valley, Colorado, on December 17, 1908, to Ora Edward Libby and Eva May (nee Rivers). After attending grammar and high schools near Sebastopol, California (1913-26), he attended the University of California at Berkeley from 1927 to 1933, taking his bachelor s and Ph.D. degrees in 1931 and 1933, respectively.

Radiocarbon chronometry was inuced by Willard Frank Libby (1908-1980) in 1949 and Libbywas awarded the obel Prize for it. The age called radiocarbon age is not calendars are as it is measured relative 1950. With half-life of 5,730 years allows dating of ground water no older than 50 thous. years. However, the use of data is difficult because of the need to account for the effect of many other processes on the formation of ground water composition (mixing, interaction with carbonate minerals, etc.). 

Willard Frank Libby (United States) for his method to use carbon-14 for age determination in archaeology, geology, geophysics, and other branches of science. Libby developed a procedure that uses the relative abundance of carbon isotopes in a sample to determine how old it is. This procedure has been extremely useful to scientists from many fields and has played a major role in establishing the ordering of historical events, including the prehistory of humankind. 

The other direction is connected with the work of Libby (1952), who suggested that a considerable part of the Frank-Condon barrier in the reaction is due to the solvent polarization. Since, in the first works of this kind, attention was paid mainly to the role played by the solvent in the reaction and since the solvent was described using the concept of the polarization of the medium per unit volume, theories of this kind are referred to in the literature sometimes as continuum ones (see, e.g.. Ref. 8).

Willard Frank Libby (1908-1980) was a professor at the University of CaHfomia from 1959 and responsible for its Geophysical Institution from 1962 to 1976. He saw the possibility in the C decay and developed a workable technique for age determination, a method that has great utility for dating of, above all, archeological finds. For this he got the Nobel Prize for chemistry in 1960. 

As a light microscopic particle, electron easily tunnels through a potential barrier, therefore, the process is governed by general tunneling law formulated by Gamov. The principle theoretical comstone for condenced-phase ET was laid by Franck and Libby (1949-1952) who asserted that the Frank-Condon principle is applicable not only to the vertical radiative processes but also to nonradiative horizontal election transfer.
