If H NMR spectrum gives relative intensity is that integration?

Question

I am interpreting H NMR graph and the y-axis says relative intensity so is that basically the integration (or at least the ratio of the integration)?

Answer 1

If you zoom in on this example NMR spectrum:

you can see that there is a sigmoidal line across each peak . That sigmoidal line is the integration for that peak, and the height between the ends of the sigmoid is a measure of the relative area of that peak.

Answer 2

The integration is the area under each peak in the spectrum. It is, roughly therefore, the product of the height and the width of the signal. Anything that increases the frequencies at which the protons take up energy will widen, and thus lower the height of the peaks.

A sharp signal will therefore be higher than one that has a wider bandwidth.

Because the peaks are curved, not linear, we must use calculus to determine the areas, Hence integration versus multiplication.

Answer 3

Sorry, yet you're unlikely to locate everyone with that style of know-how here. in case you want to be attentive to in case you need to have intercourse earlier marriage, then this is a various component altogether.
