ResumoFourier transform infrared spectroscopy (FTIR), reflection–absorption infrared spectroscopy (RAIRS) and surface-enhanced Raman spectroscopy (SERS) were applied to study the adsorption of the macrocycle sub-2,3-boronnaphthalocyanine chlorine (subBClNPc) on surfaces of different nature. The analysis of the results obtained with the above techniques as well as a semiempirical calculation suggest the existence of a significant although weak adsorbate–substrate interaction and that the compound is oriented with the Cl atom toward the metallic surface. The vibrational study was completed with a normal co-ordinate analysis (NCA).
