A model of the effects of paramagnetic oxygen molecules as centres of short relaxation times on paramagnetic carbon centres has been developed. A "Relay-race mechanism" concept has been proposed within which changes are considered from the viewpoint of the character of an interaction between carbon centres induced by oxygen molecules. The model accounts for literature data concerning on anomalous decrease of recorded intensity during oxygen molecule input. A possibility of the formation of a superlorentz line form, characterised by shallower slope of the wings as compared to the lorentz line has been demonstrated. Quantitative parameters for the line form analysis have been introduced.
