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]
Anders Jonas Ångström (Swedish: [ˈânːdɛʂ ˈjûːnas ˈɔ̂ŋːstrœm]; 13 August 1814 – 21 June 1874) was a Swedish physicist and one of the founders of the science of spectroscopy. [1] Ångström is also well known for his studies of astrophysics, heat transfer, terrestrial magnetism, and the aurora borealis.
After a long delay, he was offered the job in March 1946, but he first had to spend 3–4 months in Gordon Sutherland’s lab in Cambridge, to gain experience in the new field of infrared molecular spectroscopy. This led to a paper on the structure of phthiocerane, [5] the hydrocarbon derived from phthiocerol, found in tubercle bacilli. [6]
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.
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.
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 ...
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 ...
Edward Teller (Hungarian: Teller Ede; January 15, 1908 – September 9, 2003) was a Hungarian-American theoretical physicist and chemical engineer who is known colloquially as "the father of the hydrogen bomb" and one of the creators of the Teller–Ulam design based on Stanisław Ulam's design.
