Nv. Belova et al., STRUCTURE AND ENERGY STUDIES OF BETA-DIKETONATES .4. VIBRATIONAL CHARACTERISTICS OF Y(DPM)(3) AND Y(DPM)(2), Journal of structural chemistry, 38(3), 1997, pp. 386-394
The vibrational problem for the Y(DPM)(3) and Y(DPM)(2) molecular form
s that are present in the overheated vapor of yttrium tris-dipivaloylm
ethanate is solved. For this purpose, the experimental Raman spectra o
f 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 perpendi
cular displacements to the internuclear distances of the two molecular
forms needed for interpreting electron diffraction data are calculate
