Abstract
THE following relations may be useful in discussions of the isotopic effect in Hainan spectra. Let vi and vi be corresponding frequencies of the isotopic molecules, ma and ma the masses of the isotopic atoms and Aab the constants of the vibrational potential energy ; then Similar equations hold for the 6th, 8th and following powers of the frequencies. The equations may be applied to each symmetry class separately, if symmetry co-ordinates are suitably chosen.
