Chapter 3.3, Problem 3.22P

Interpretation Introduction

Interpretation:

The number of protons giving rise to each signal in the spectrum of a compound with molecular formula $C_7{H}_{14}O$ has to be determined.

Concept Introduction:

Integration is one of the characteristics of proton NMR spectrum which is the area under each signal.  After acquiring a spectrum, a computer calculates the area under each signal, and then displays this area as a numerical value placed under the signal which is relative only.

In order to convert the integration values into useful information, a smallest number should be chosen and then all integration values should be divided by this number.  If the numerical values are not whole numbers, then in order to arrive at whole numbers all the numbers should be multiplied by a suitable integer.
