atomic spectrum n. Physics and Chemistry a spectrum of the light emitted or absorbed by an atom as a result of its orbital electrons passing from one energy level to another, and generally characteristic of the element concerned.

ΚΠ

1873 Proc. Royal Soc. 22 372 In iodine, the short lines, brought about by increase of density in an atomic spectrum, are represented by the addition of a system of well-defined ‘beats’ and broad bands.

1958 E. S. Gilreath Fund. Concepts Inorg. Chem. ii. 88 Since atomic spectra arise from electrons being excited to levels above their ground states, a minimum amount of energy must be supplied to produce the excitation.

2003 M. Roos Introd. Cosmol. (ed. 3) iii. 62 In a strong gravitational field these clocks run slower, so the atomic spectra shift towards lower frequencies.
