The method of taking into consideration the anharmonicity proposed by Majanc, and hitherto never checked on any molecule with known harmonic frequen- 118 M. Rytel des hass been used. The harmonic frequencies of isotope molecules of water, and force constants have been calculated the results obtained were
in accordance with those obtained previously. The fundamental molecule frequencies from tritium have been foreseen; they are in accordance with the partiel experimental data of Staats, Morgan and Goldstein.
