Draw the Lewis structure and describe the bonding in Cr2(CH3COO)4(H2O)2 using MO theory. In the Raman spectrum an intensive line at 556 cm-1 is observed. Assign this band and calculate the force constant using the approach that only two atoms are involved in this vibration. (For comparison: Cd22+ 111 N/m and Hg22+ 169 N/m)

Why is 133C-133C spin-spin splitting not observed in ordinary organic compounds?
Use group theory to predict the number of v(CO) stretching vibrations you would expect to observe in the IR and Raman spectra of cis and trans isomers of Mo(CO)4(PPh3)2. Can these isomers be differentiated by vibrational spectroscopy? (ii) Can these isomers be differentiated by 31P{H} and 13C {¹H} spectroscopy? Fully explain your answer in both cases explaining what you would expect to see in each spectrum. (iii) Reaction of both isomers with more PPh3 affords mixtures of fac and mer isomers of [Mo(CO)3 (PPh3)3]. Give the point groups for each. Can they be distinguished by IR spectroscopy?

In the characterization of the acid content of petroleum crude, a scientist found the acidic carbonyl (C=0) bond at 1685 cm-1 in the measured Raman spectra. If a blue laser line at 488 nm was used, calculate the laser frequency the absolute frequency of the C3DO stretching mode. iii) If a red laser at 633 nm was used for the analysis, what is the laser frequency and what is the absolute frequency of the C=0 at this wavelength?
Vibrational spectroscopy has played a role in supporting the pentagonal bipyramidal structure of the ion IO2F5 2-. Raman spectroscopy of the tetramethylammonium salt of this ion shows a single absorption in the region expected for I=O stretching vibrations, at 789 cm-1 . Is a single Raman band consistent with the proposed trans orientation of the oxygen atoms?
