4 Atomic spectra and energy levels The Rydberg formula (Johannes Rydberg, 1888) relates the frequencies of spectral lines with the transitions between energy levels in the atom. The following form of the equation is for hydrogen:  = R H 1 n 1 2 1 n 2 2 n 1 n 2 R H = 3.29 × 10 15 Hz E n = − hR H n 2 n is the principle quantum number
