Question
Chapter 16, Problem 16.26E
Interpretation Introduction
Interpretation:
The magnetic field strength that is required to achieve resonance between the two spin states of an electron on a compound is to be predicted.
Concept introduction:
Electron spin resonance is the method to study the materials with an unpaired electron. An unpaired electron absorbs the microwave radiation under the strong magnetic field. The difference between two energy levels is calculated by the formula shown below.

- 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.arrow_forward7.

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.
