Excimer molecules. Halogenides of noble gases.

In the paper, molecules formed on the basis of the noble-gas monohalogenides are considered. ELectron and rotatinal structure of excimer molecules is considerd. Occurrence of some specific levels, conditioned by a small coupling energy in the ground state of molecules of the noble-gas monohalogenides is discussed. Main attention is paid to the electron and rotational structure of XeCl and XeF molecules.
