Rydberg Constant

Rydberg Constant
Definition:Fundamental atomic constant, which is used to calculate the wavelength λ of spectral lines of atoms according to the general formula 1/λ = Z2 R (ni-2 - nf-2), where Z = charge of the atomic nucleus, ni = main quantum number of the initial state, and nf = main quantum number of the final state. R for a specific atom is calculated according to: R = R / (1 + me/M), where R represents the infinity Rydberg constant, me the rest mass of the electron, and M the mass of the atomic nucleus, respectively. The Rydberg constant is given by R = me4 / 8 ε02 h3 c , where me = rest mass of the electron, ℯ = elementary charge, h = Planck constant, c = velocity of light, and ε0 = permittivity of vacuum.
