| Abstract: | The vibrational problem for the Y(DPM)3 and Y(DPM)2 molecular forms that are present in the overheated vapor of yttrium tris-dipivaloylmethanate is solved. For this purpose,
the experimental Raman spectra of Y(DPM)3 solutions are interpreted. The force field of the Y(DPM)2 radical is estimated on the basis of the force constants determined for Y(DPM)3. Rms vibrational amplitudes and corrections for perpendicular displacements to the internuclear distances of the two molecular
forms needed for interpreting electron diffraction data are calculated.
