Abstract
The rovibrational structure of the transitionA 2π —X 2Σ of the van der Waals molecules NaAr and NaKr has been investigated by means of high resolution laser spectroscopy applying the techniques of laser-induced fluorescence and of optical-optical double resonance to the molecules in a supersonic beam. Precise values for the parameters of rotation have been obtained for theX 2Σ state of NaKr84. By means of an investigation of the spectral distribution of the fluorescence light the repulsive part of theXΣ-potential of NaKr has been determined. Local perturbations have been detected in theA 2π states of both NaAr and NaKr and a full deperturbation analysis has been performed.
