Interpretation Introduction

(a)

Interpretation:

The 1H and 19F spectra of FC2H should be predicted.

Concept introduction:

Spin-spin coupling is a phenomenon which is caused by the spin coupling between two chemically different nuclei which are NMR active. This effect is indicated through peak splitting in NMR spectra. Coupling constant is a measure of interactions between NMR active nuclei.

Interpretation Introduction

(b)

Interpretation:

The 1H and 19F spectra of CF3CH3 should be predicted.

Concept introduction:

Spin-spin coupling is a phenomenon which is caused by the spin coupling between two chemically different nuclei which are NMR active. This effect is indicated through peak splitting in NMR spectra. Coupling constant is a measure of interactions between NMR active nuclei.

Interpretation Introduction

(c)

Interpretation:

The 1H and 19F spectra of (CH3)CF should be predicted.

Concept introduction:
