Spectroscopy | ESO
The first astronomical application of spectroscopy was in the analysis of sunlight by Fraunhofer and Kirchhoff, in the early 19th century. It was expected that the white light emitted from the Sun would
Spectroscope, Kirchhoff-Bunsen
It was with the introduction of the spectroscope by Bunsen and Gustav Robert Kirchhoff (1824-1887) in 1860 that the detection of further elements became possible.
Spectroscopy (1855-1864) | Chemistry | University of
In 1859, Robert Wilhelm Bunsen (1811-1899) and Gustav Robert Kirchhoff (1824-1887) developed the modern version of this instrument called a flame
History of the Origin of the Chemical Elements and Their Discoverers
Although the atomic weight of an element and spectral analysis of that element were not available in the early days, both of these elemental properties would be required before discovery of
Spectrometers for Elemental Spectrochemical Analysis,
Following a discussion of the basic modules of spectrometer systems in Part I, the author continues his series on spectrochemical analysis with a

This first spectroscope was nearly in modern form. Newton'' s analysis of light was the beginning of the science of spectroscopy. It gradually became clear that the sun''s radiation has components outside
Robert Bunsen and Gustav Kirchhoff
Between 1855 and 1860, Bunsen and his colleague Gustav Kirchhoff developed a spectroscope that focused the light from the burner flame onto a prism that separated this light into its spectrum.
Mass spectrometry—The early years
Early work in Chemistry had, through the laws of simple and multiple proportions in stoichiometry lead Dalton in 1808 to conclude that chemical reactions appeared to involve the
