摘要：

The present paper gives the results of laboratory investigations of the radiation fine-structure spectra of free molecules of a number of PAHs in the field of the first electronic transition. The objective laws found by us for the first time and connected with the multiplet of the fine structure of the vibronic spectra of PAHs free molecules are compared with the data obtained under conditions of the low temperature matrix isolation. Results of the given investigations together with the previously published ones can serve the base for the critical analysis of the brought up hypotheses on the nature of the PAHs origin and state in the astronomic objects.
