Increasing and Decreasing Intensity

The two buttons under the 'View Ribbon' allow the user to interactively scale the data of the NMR spectrum. This operation does not modify the acquisition or the MestreNova data file; it only magnifies or diminishes the representation of the data which you see on your screen. You can also use the '+ key' to increase or the '- key' to decrease the intensity and the same effects may be obtained by rotating the scroll wheel of the mouse.

The intensity increases/decreases 10 times slower if the user press the Ctrl/Cmd key while moving the mouse wheel.
