Recently, the rovibronic absorption and emission spectra of diatomic
molecules dressed by medium-intensity laser fields have been discussed.
By computing the total absorption probability as a function of dressing
wavelength an asymmetric line shape has been obtained strongly
resembling to the well-known Fano line shape. Applying two-state
analytical and three-state numerical models the shape of the total
absorption probability function is explained. Further confirmation of
the model based results is provided by high resolution accurate
numerical computations using large number of basis functions.
