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]
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 ...
A spectrometer is used in spectroscopy for producing spectral lines and ... The term was first used in 1876 by Dr. Henry Draper when he invented the earliest ...
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.
By 1814, Fraunhofer had invented the modern spectroscope. [10] In the course of his experiments, he discovered a bright fixed line which appears in the orange color of the spectrum when it is produced by the light of fire. This line enabled him afterward to determine the absolute power of refraction in different substances.
Invented by Arnold O. Beckman in 1940 [disputed – discuss], the spectrophotometer was created with the aid of his colleagues at his company National Technical Laboratories founded in 1935 which would become Beckman Instrument Company and ultimately Beckman Coulter. This would come as a solution to the previously created spectrophotometers ...
Raman had invented a type of spectrograph for detecting and measuring electromagnetic waves. [ 34 ] [ 78 ] Referring to the invention, Raman later remarked, "When I got my Nobel Prize, I had spent hardly 200 rupees on my equipment," [ 79 ] although it was obvious that his total expenditure for the entire experiment was much more than that. [ 80 ]
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]
