In this work, the spectrum of molecules in organic semiconductors is considered as a random process excitations of strongly correlated states. Therefore, the energy spectrum of a molecule is represented using the autocorrelation function, transitions frequency. To calculate the probability of electronic transitions in the UV region is entered relative the empirical autocorrelation parameter μ, which is equal to the ratio of the energy spectrum in the UV region to the energy of the whole electronic spectrum. A correlative relation between the ionization potential (electron affinity) and the parameter μ of polycyclic aromatic hydrocarbons.
