WebNov 4, 2014 · Continuous spectra (absorption or emission) are produced when (1) energy levels are not quantized, but continuous, or (2) when zillions of energy levels are so … There are emission lines from hydrogen that fall outside of these series, such as the 21 cm line. These emission lines correspond to much rarer atomic events such as hyperfine transitions. [1] The fine structure also results in single spectral lines appearing as two or more closely grouped thinner lines, due to … See more The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between … See more The energy differences between levels in the Bohr model, and hence the wavelengths of emitted or absorbed photons, is given by the Rydberg formula: See more • Astronomical spectroscopy • The hydrogen line (21 cm) • Lamb shift • Moseley's law • Quantum optics See more A hydrogen atom consists of an electron orbiting its nucleus. The electromagnetic force between the electron and the nuclear proton leads … See more The concepts of the Rydberg formula can be applied to any system with a single particle orbiting a nucleus, for example a He ion or a muonium exotic atom. The equation must be … See more • Spectral series of hydrogen animation See more
WebHere we have talked about emission and absorption lines from hydrogen, the simplest atom in the universe. Of course, there are characteristic lines from many-electron atoms, such as oxygen, nitrogen, neon, iron, and practically every other element. ... by B.H. Bransden and C.J.

WebH i Lyα (1215.67 Å) and the O i triplet (1302.17, 1304.86, and 1306.03 Å) are bright far-ultraviolet (FUV) emission lines that trace the stellar chromosphere. Observations of stellar Lyα and O i using the Hubble Space Telescope's (HST) most sensitive FUV spectrograph, the Cosmic Origins Spectrograph (COS), are contaminated with geocoronal emission, …
WebEach emission line consists of a single wavelength of light, which implies that the light emitted by a gas consists of a set of discrete energies. For example, when an electric discharge passes through a tube containing hydrogen gas at low pressure, the [latex]\ce{H2}[/latex] molecules are broken apart into separate [latex]\ce{H}[/latex] atoms ... The Balmer series is particularly useful in astronomy because the Balmer lines appear in numerous stellar objects due to the abundance of hydrogen in the universe, and therefore are commonly seen and relatively strong compared to lines from other elements. The spectral classification of stars, which is primarily a determination of surface temperature, is based on the relative strength of spectral lines, and the Balmer series in particular is very import…
