The phrase "atomic spectrum" is correct and usable in written English.
It can be used in scientific contexts, particularly in discussions about the emission or absorption of light by atoms.
Example: "The atomic spectrum of hydrogen consists of distinct lines that correspond to specific energy transitions."
Alternatives: "atomic emission spectrum" or "atomic absorption spectrum".
In 1931 Urey and two collaborators detected deuterium by its atomic spectrum in the residue of a distillation of liquid hydrogen.
In an atomic spectrum, each transition corresponding to absorption or emission of energy will account for the presence of a spectral line.
Inasmuch as the wavelengths of atomic spectral lines are characteristic of the element, the atomic spectrum may be used for identifying the element.
Urey and two colleagues then detected deuterium by its atomic spectrum in residue distilled from liquid hydrogen.
If (X1, μ1) and (X2, μ2) are G-spaces with finite invariant measures and the action of G has purely atomic spectrum (and is essentially free or essentially transitive) we prove that every measure preserving Γ-map φ: X1 → X2 is also a G-map.
The meter bar was replaced as the definition of the fundamental unit of length in 1960 by a line in the atomic spectrum of krypton, but the kilogram prototype is still the international standard of mass.
a For circular orbits, the lowest ones in each atomic shells – including the valence ones, one has ΔO=Δr=2πr, with r the orbital radii thereof, while O=p is the fixed particle's momentum on that orbit; therefore, when combined into eq. (18b) they provide the celebrated Bohr-de Broglie relationship rp=nħ solving the atomic spectra of Hydrogen atom in principal quantum numbers (n).
Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another.
Thomson subsequently proposed his "plum pudding" model of the atom, but that model could neither predict nor explain observed atomic spectra such as the Balmer spectrum of hydrogen.
He was one of the great pioneers in developing the theory of atomic spectra proposed by Niels Bohr.
He became an indefatigable worker on atomic spectra, energetically untangling the confusing patterns of spectral lines for elements like titanium and yttrium.
