Chapter 13, Problem 13.50AP
Interpretation Introduction

(a)

Interpretation:

The number of lines expected in the proton NMR of +NH4 is to be stated. The intensity of each line is to be stated.

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. Tetramethylsilane (TMS) is taken as reference.

Interpretation Introduction

(b)

Interpretation:

The number of lines expected in the 13C NMR of CDCl3 is to be stated.

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.

Interpretation Introduction

(c)

Interpretation:

An explanation as to how the samples of the compounds H2CDI, D2CHI, and D3CI can be distinguished from each other by proton NMR spectrum is to be stated. The other technique that can be used is to be stated.
