Chapter 16, Problem 16.38E
Interpretation Introduction
Interpretation:
Whether ESR spectroscopy differentiate between a tetrahedral structure and a square planar structure for the
Concept introduction:
In the ESR spectroscopy, the sample is exposed to the monochromatic microwave radiation and varying magnetic field. In the magnetic field, the splitting of spin occurs between the two spin states having different directions. These have different energies. The exposure of the

13C NMR spectroscopy provides valuable information about the environments of a molecule's carbon atoms. Since carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet.
Draw an isomer of C5H11Cl that would be expected to have four resonances in its 13C NMR spectra.
If a hypothetic vibrational motion of a molecule can be described by
Tvib = 2A1 + E, within the point group Cav, how many bands/peaks would you
expect to see in its IR spectrum? Explain your reasoning.

Let ωCH be the angular frequency of the C-H bond stretching vibration observed in theIR spectrum of an organic molecule. (Note that angular frequency ω = 2πν). EstimateωC2H, the bond stretching frequency when 1H is substituted by 2H in the molecule.(Express ωC2H in terms of ωCH).

- Vibrational Spectroscopy When an atom in a bond is replaced with a different isotope of the same element, the reduced mass of the bonded atoms change the absorption of the vibration in the infrared (vibrational) spectrum. The wavenumber of a vibration is given by v = ¹, where k = force constant of the bond, μ = 2π reduced mass. Reduced Mass: μ = 1 " where m₁ and m2 are the mass of each attached atom. Assuming the force constant of a particular pair of atoms does not change when one or the other atom is substituted with an isotope, the magnitude of the vibrational shift can be determined from a ratio of the two vibrations.
