Laser spectroscopy is a spectroscopic technique that uses lasers to be able determine the emitted frequencies of matter. [87] The laser was invented because spectroscopists took the concept of its predecessor, the maser, and applied it to the visible and infrared ranges of light. [87]
Ellis Ridgway Lippincott Jr. (July 6, 1920 – December 24, 1974) was an American chemist, educator, inventor, science leader, and pioneer in spectroscopy. He was a professor of chemistry at the University of Maryland from 1955-1974 and served as director of the Center for Materials Research.
His optical work was important as well, where he is remembered for his observations of dark gaps in the solar spectrum (1802), [7] [8] a key event in the history of spectroscopy. He invented the camera lucida (1807) which contained the Wollaston prism (the four-sided optics of which were first described basically by Kepler) [9] and the ...
An example of spectroscopy: a prism analyses white light by dispersing it into its component colors. Spectroscopy is the field of study that measures and interprets electromagnetic spectrum. [1] [2] In narrower contexts, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum.
A Calutron is a sector mass spectrometer that was used for separating the isotopes of uranium developed by Ernest O. Lawrence [11] during the Manhattan Project and was similar to the Cyclotron invented by Lawrence.
Hertz's grandnephew Hermann Gerhard Hertz, professor at the University of Karlsruhe, was a pioneer of NMR-spectroscopy and in 1995 published Hertz's laboratory notes. [ 48 ] The SI unit hertz (Hz) was established in his honor by the International Electrotechnical Commission in 1930 for frequency , an expression of the number of times that a ...
He developed diffraction grating and also invented the spectroscope. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines. [2] The German research organization Fraunhofer Society, which is Europe's biggest Society for the advancement of applied research, is named after him.
Robert Wilhelm Eberhard Bunsen (German:; 30 March 1811 [a] – 16 August 1899) was a German chemist.He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. [11]
