- We calculated that the resonance frequency of an 1H in the presence of an 11.74 tesla magnet was 500MHz, and we later saw that a 13C nucleus resonantes at approximately 125 MHz in this same magnetic field. What is the resonance frequency of a 19F nucleus in the presence of an 11.74 tesla magnet?arrow_forwardExplain 1H NMR: Spin-Spin Splitting ?arrow_forwardThe organic compound 1,4-dimethylbenzene (also known as p-xylene) has the formula (CH3)2C6H4. Its structure has two CH3 (methyl) groups substituted at opposite positions on the benzene (C6H6) ring. Predict the number of peaks in the low-resolution proton NMR spectrum of this compound and the relative areas of the peaks.arrow_forward
- 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?

- You are considering purchasing a new NMR instrument so that you can do H1 NMR. Suppose one instrument would provide a magnetic field of 10T and another would provide a field of 3T. For a given molecule, would these two instruments have two different absorption wavelengths between spin states? If so, calculate the two different wavelengths that would cause absorption, ignoring the itnernal magnetic field of the molecule.arrow_forward(a) Calculate the energy difference between the two spin states of 1H and of 13C in a magnetic field of 6.8 T. 1H 4.0 1.19e-25 X J 13C 4.0 J (b) What is the precession frequency of a 1H nucleus at this magnetic field?
