Web1 λ = − ℜ( 1 n2 2 − 1 n2 1) Except for the negative sign, this is the same equation that Rydberg obtained experimentally. The negative sign in Equation 7.3.5 and Equation 7.3.6 indicates that energy is released as the electron moves from orbit n2 to orbit n1 because orbit n2 is at a higher energy than orbit n1. WebThe mercury spectrum has been studied for many years. A list of 92 lines claimed as due to mercury was published by Kayser and Runge1 in 1891.
