Definition

spectroscopic constant that determines the wave numbers of the lines in the spectrum of hydrogen:

R_{\infty} = \frac{e^{2}}{8 π ε_{0} a_{0} h c_{0}}

where

$e$ :: is the elementary charge (ISO 80000-1),

$ε_{0}$ :: is the electric constant (IEC 80000-6: Electromagnetism),

$a_{0}$ :: is the Bohr radius (Bohr radius),

$h$ :: is the Planck constant (ISO 80000-1), and

$c_{0}$ :: is the speed of light in vacuum (ISO 80000-1)
