Concept explainers

NMR Spectroscopy

NMR stands for Nuclear Magnetic Resonance in which the study of different molecules is done based on the interaction of radiofrequency electromagnetic radiations with the nuclei of molecules placed in a strong magnetic field. A precise study of spectra of visible light and all bands of electromagnetic radiation is called spectroscopy.

The protein haemerythrin (Her) is responsible for binding and carrying O2 in some invertebrates. Each protein molecule has two Fe2+ ions that are in very close proximity and work together to bind one molecule of O2, form ing an Fe2O2 group. (a) The Raman spectrum of oxygenated haemerythrinobtained with laser excitation at 500 nm has a band at 844 cm-1 which has been attributed to the O-O stretching mode of bound 16O2. Why is Raman spectroscopy and not infrared spectroscopy the method of choice for the study of the binding of O2 to haemerythrin? (b) Proof that the 844 cm-1band in the Raman spectrum of oxygenated haemerythrin arises from a bound O2 species may be obtained by conducting experiments on samples of haemerythrin that have been mixed with 18O2, instead of 16O2 . Predict the fundamental vibrational wavenumber of the 18O-18O stretching mode in a sample of haemerythrin that has been treated with 18O2. (c) The fundamental vibrational wavenumbers for the O-O stretching modes of O2,…

It might be unexpected that the Karplus equation, which was first derived for 3JHH coupling constants, should also apply to three-bond coupling between the nuclei of metallic elements such as tin. T.N. Mitchell and B. Kowall (Magn. Reson. Chem. 33, 325 (1995)) have studied the relation between 3JHH and 3JSnSn in compounds of the type Me3SnCH2CHRSnMe3 and find that 3JSnSn = 78.86 Hz and 3JHH =27.84 Hz. (a) Does this result support a Karplus type equation for tin nuclei? Explain your reasoning. (b) Obtain the Karplus equation for 3JSnSn and plot it as a function of the dihedral angle. (c) Draw the preferred conformation.
