One effect that affects these things can be investigated with a Lummer-Gehrcke plate. When these thingsare affected by impact pressure, quasistatic pressure, and the Doppler effect, they can be modeled by aVoigt profile. The distance between two of these things due to that effect is proportional to the magneticquantum number multiplied by the Bohr magneton. Kirchhoff's laws govern the production of these thingsby hot and cold gases. The D1 and D2 examples of these things created the "sodium doublet" in a seriesnamed for Fraunhofer. During a solar eclipse, examination of these things led Jules Janssen to discoverhelium
