Abstract
Absolute concentration measurements by ESR spectroscopy require the determination of integrated intensities. It is shown that the commonly employed first moment method can lead to serious errors when applied to Lorentzian lines. These errors result from neglecting the area in the wings of these lines. A general correction curve for modulation-distorted lines is presented. The use of oxygen for the calibration of ESR spectrometers is discussed.This publication has 14 references indexed in Scilit:
