Vibrational spectra of ammonium ammine-oxo-diperoxovanadate

Infrared and Raman spectra of solid NH4[VO(O2)2NH3], ND4[VO(O2)2ND3], 14/15NH4[VO(O2)214/15NH3] (about 50% 15N) and Raman spectrum of solution of NH4[VO(O2)2NH3] have been measured. Interpretation of the spectra was complemented by normal coordinate analysis in the approximation of point mass model (NH3). The results have shown that there exists coupling of vibrations of two V(O2) groups, which enables an explanation of differences between spectra of the mono- and diperoxo complexes. The vibrational coupling of VO and OO bonds within one V(O2) group probably causes small sensitivity of wave number of v(O-O) band to changes of d(O-O) bond length.

Tetramethylammonium Salts

The infrared and Raman spectra of potassium and tetramethylammonium salts of the dinuclear anions M2OX104- and M2NX8(H2O)23-, with M=Ru, Re and X=Cl, Br, have been registered and assigned on the basis of a normal coordinate analysis. The totally symmetric vibrations νsΜ2Ο (νsM2N), νsMXa,x(νsM—OH2) and δsOMX (δsNMX) show considerable mixing. The force constants of the bridge bonds are 3.9 mdyn/Å for the μ-oxo-and 5.1 mdyn/Å for the μ-nitrido-compounds, the respective stretch-stretch interaction constants 0.45 and 0.6 mdyn/Å.

Overlapping Bands

Raman spectra (1 600 - 100 cm-1) of liquid S2O5F2 and Se2O5F2 and infrared spectra of liquid and gaseous S2O5F2 were measured. A modified general valence force field was used for their interpretation by normal coordinate analysis. Refinement of the number of lines in the Raman spectrum of S2O5F2 by means of numerical separation of the overlapping bands led to the conclusion that liquid S2O5F2 consists at least of three rotamers at room temperature.

Absorbance Peak

Infrared, Raman, and resonance Raman data are reported for ethyl and methyl dithioacetate together with data for their isotopically substituted analogs: CD3C(=S)SCH3, CH3C(=S)SCD3, 13CH3C(=S)SCH3, CH313C(=S)SCH3, CD3C(=S)SCH2CH3, CH3C(=S)SCD2CH3, and CH313C(=S)SCH2CH3. Based on these data and a normal coordinate analysis of methyl dithioacetate, assignments are proposed for the majority of bands appearing in the vibrational spectra. Using excitation wavelengths in the 324–356 nm region strong intensity enhancement is observed for Raman bands near 1195, 1100, 730, and 580 cm−1 which are assigned to stretching motions of the CCSSC skeleton. Raman excitation profiles are reported for the 1197 and 581 cm−1 bands of ethyl dithioacetate and the electronic absorbance peak near 305 nm is identified as the source of resonance Raman intensity enhancement.
