dc.description.abstractA number of sets of valence force constants and the corresponding normal modes have been calculated for several bent symmetrical $XY_{2}$ molecules and their isotopic forms. For each molecule, these sets, which exactly reproduce the observed vibrational wave numbers, lie within a limited range. Two of the sets have the special feature that they closely reproduce the observed wave numbers for the isotopic molecules. For the case of $H_{2}O$ and $D_{2}O$, the only molecules for which the harmonic vibrational wave numbers are well known, the allowable range for the O-H stretching force constant, $F_{d}$, is from 5.050 to $8.428 md/{\AA}$. The upper limiting value leads to a somewhat better agreement between the observed and calculated wave numbers and is found to be in very good agreement with calculations of earlier investigations. For each molecule, the set associated with the lower limit, is characterized by large interaction force constants. The symmetrical normal modes associated with this set have directions of motion which differ by approximately $90^{\AA}$ from those corresponding to the upper limit.en_US
