Chapter 13, Problem 13.5P
Interpretation Introduction

(a)

Interpretation:

The chemical-shift difference in ppm of two resonances separated by 45Hz at operating frequency 60MHz is to be calculated.

Concept introduction:

Many nuclei and electrons have spin. Due to this, spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin. The difference between its resonance frequency and that of the reference standard is known as the chemical shift of a nucleus.

Interpretation Introduction

(b)

Interpretation:

The chemical-shift difference in ppm of two resonances separated by 45Hz at operating frequency 300MHz is to be calculated.

Concept introduction:

Many nuclei and electrons have spin. Due to this, spin magnetic moment arises. The energy of this magnetic moment depends on the orientation of the applied magnetic field. In NMR spectroscopy, every nucleus has a spin. There is an angular momentum related to the spin.

1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)
