Özet

The relationships between the theoretical values calculated using density functional theory and experimental data derived from the differential scanning calorimetry of high-energy organic compounds are studied. The theoretical values are the number of atoms and bonds of different types and their lengths, minimum eigenfrequencies, atomization energies, ionization potentials, electron affinities, and frontier orbital energies. The experimental data are the amounts of releasing heat (the first peaks higher than 1 kJ g(-1)) and corresponding temperatures. Neural networks and regression, factor, discriminant, and cluster analysis are applied to find the dependencies between theoretical values and experimental data. It is found that the heat amount cannot be predicted in the general cases, whereas the corresponding temperature can be predicted with a neural network with an accuracy of approximate to 30 degrees C. Cluster and discriminant analysis provides the way for the classification of high-energy compounds into three groups. Some of these groups require particular rules for the prediction of experimental data from the theoretical values.
