Popis:	Calibration curves are shown for intensity and phase corrections in FT NMR. Algebraic expressions are proposed for a theoretical simulation of these curves and for digital intensity, phase, and baseline corrections of the spectrum, as well as automatic procedures to recognize signals free from any dispersion component and thus to determine convenient phase angle values. Digital corrections are shown to be necessary for obtaining a high level of accuracy in measuring integrated signals areas; e.g., the uncertainty range in determining the aromaticity factor of oil samples was reduced from ca. 4 to 1% in this way.
