A model for describing the transient molecular behavior in hot dense plasmas is presented and applied to the case of a transient F8+/F9+ molecular ion embedded in a dense (N-e approximate to 10(23) cm(-3)) fluorine plasma. Electron screening effects on molecular energy levels and on dipolar matrix elements are investigated for specific plasma conditions. The accuracy of the calculations is tested comparing values of the polarization shift of the FLy beta line as calculated from the present model to the ones determined in the framework of the Ion Sphere Model (ISM).
