eng	New Aspects of Impact Reactivity of Polynitro Compounds. Part II. Impact Sensitivity as "the First Reaction" of Polynitro Arenes	The impact reactivity (?the first reaction?) of 22 polynitro arenes was expressed as the drop energy, Edr,, required for 50 percent initiation probability. Relationships have been found between the Edr values and heats of fusion, on the one hand, and 13C NMR chemical shifts of carbon atoms in reaction centers, on the other. On the basis of the said relationships it was stated that the impact reactivity of polynitro arene molecules depends on the electronic configuration within their reaction centers and intensity of their intermolecular interactions in the molecular crystals. The relationships found make it possible to specify this reaction center which is illustrated on molecules of 1,5-dinitronaphthalene and 3,3´-dimethyl-2,2´,4,4´,6,6´-hexanitrodiphenylsulfide.	impact sensitivity, polynitro arenes, 13C NMR chemical shifts, heat of fusion
