The stretching frequencies for H2, HD, and D2 are 4395, 3817, and 3118 cm-1 respectively. Why? Explain.
Suppose that three conformations are proposed for the nonlinear molecule H2O2 (1, 2 , and 3).The infrared absorption spectrum of gaseous H2O2 has bands at 870, 1370, 2869, and 3417 cm-1. The Raman spectrum of the same sample has bands at 877. 1408, 1435, and 3407 cm-1. All bands correspond to fundamental vibrational wavenumbers and you may assume that (i) the 870 and 877 cm-1 bands arise from the same normal mode, and (ii) the 3417 and 3407 cm-1 bands arise from the same normal mode. (a) If H2O2 were linear, how many normal modes of vibration would it have? (b) De termine which of the proposed conformations is inconsistent with the spectroscopic data. Explain your reasoning.
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?
The IR spectrum of HCN shows three strong absorption band at 3312 cm⁻¹, 2089 cm⁻¹ and 712 cm⁻¹ from this information alone can you deduce whether HCN is linear or nonlinear? Assuming that HCN is linear assign vibration to the three absorption bands.
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?
