[edit] Wrong units

The given formula for the Rydberg constant R_\infty would lead to a dimension of mass times velocity, whicjh is obviously not an inverse length. DumbBoy 12:09, 11 October 2005 (UTC)


The formula is correct, see eg http://scienceworld.wolfram.com/physics/RydbergConstant.html I don't like the line about being well determined due to containing 5 other constants. This needs clarifying (if it's even right), it seems to me that the errors from all the other measurements add, making the Rydberg by far the most errored.

The above user refers to a paragraph that I'm now removing:

As the formula for the Rydberg constant contains no less than five other physical constants, namely the elementary charge e \, the electron rest mass m_e \, the permittivity of vacuum \epsilon_0 \, reduced Planck's constant \hbar \, and the speed of light in vacuum c \, it is one of the most well-determined physical constants. Measuring the Rydberg constant confirms the proportions of the values of the other five constants.

[edit] Info from former page "Rydberg"

"The Rydberg is a unit of energy defined in terms of the ground state energy of the Hydrogen atom (see Rydberg formula). E=\frac{-m_e e^4}{2\hbar^2}\frac{Z^2}{n^2} The Rydberg is abbreviated Ry. 1 Ry = \frac{-m_e e^4}{2\hbar^2} = 13.6 eV"

I don't know how correct this info is, so i'm putting it here for now. Fresheneesz 23:16, 17 April 2006 (UTC)
