![]() ![]() We can manually measure the lengths by which the horizontal line is displaced at each peak to attain a ratio of hydrogens from the various signals. The pen then moves horizontally until another signal is reached, at which point, another vertical marking is made. To show these integrations, a recorder pen marks a vertical line with a length that is proportional to the integrated area under a signal (sometimes referred to as a peak)- a value that is proportional to the number of hydrogens that are accountable for the signal. NMR machines can be used to measure signal intensity, a plot of which is sometimes automatically displayed above the regular spectrum. The integrated intensity of a signal in a 1H NMR spectrum (does not apply to 13C NMR) gives a ratio for the number of hydrogens that give rise to the signal, thereby helping calculate the total number of hydrogens present in a sample.We can get the following information from a 1H Nuclear Magnetic Resonance (NMR) structure: ![]()
