The Rydberg constant, often denoted as R∞, originally defined empirically in terms of the spectrum of hydrogen, is given a theoretical value by the Bohr theory of the atom as:[1]
The best value (in 2005) was:[2]
- R∞/(hc) = 10 973 731.568 525 (8) m−1,
where h = Planck's constant and c = speed of light in vacuum.
