biotr computes LS and LSJ transitions.
##### . label . initial state . final state . Atomic weight, principal quantum number '(/A5,I3,A5,I2)' . Energy initial, label of dominant transition . Energy final, label of dominant transition . LS transition energy, wavelength in vacuum, wavelength in air .
