We present UVES (Ultraviolet and Visual Echelle Spectrograph) observations of a sample of Herbig Ae/Be stars for which we had already measured the amount of circumstellar molecular hydrogen (H_2) using the FUSE (Far Ultraviolet Spectroscopic Explorer) satellite. The preliminary analysis of these spectra confirms the well known problem of the formation and excitation of the molecules in the circumstellar environments of our sources, especially those of CH and CH^+. In the future, combined to our H_2 data, these new observations should allow us to constrain the chemical mechanisms of formation/destruction and excitation of these different molecules.
