[Effect of substituents on the heat of sublimation of nucleic acid nitrogenous bases].
Experimental results of the studieds of sublimation heats of some derivatives of nitrous bases of nucleic acids are presented. Effect of some substitutors on sublimation heats of purine and pyrimidine bases has been studie. The problem of the role of different intermolecular interactions in the stabilization of nitrous bases crystal structure is discussed on the basis of the data obtained.
