diff wavenumber lines in spectrum of Isotopes

because as in the Bohr theory it is assumes that nucleus is stationary other thn the rotation on its axis , but it can only be true if its mass is infinite , it oscillates about the center of gravity. so reduced mass of the electron is

mu = m M / m + M

where m - mass of the electron , mu - reduced mass , M - mass of the nucleus
