摘要
The molecular organization in evaporated submicron thin solid films of five phthalocyanine complexes and the metal-free phthalocyanine was studied using the propensity rules and the intensity theory of molecular vibrations in the electric dipole approximation. The spatial anisotropy was probed using transmission FTIR spectroscopy of films formed onto a KBr surface, and reflection absorption FTIR spectroscopy (RAIRS) of the films fabricated onto smooth silver and aluminum surfaces. The effect of the substrate and of the film thickness on molecular organization in the thin films is discussed. The vibrational IR and Raman (spontaneous, resonance Raman, and surface-enhanced resonance Raman SERRS) spectra of the fluorogallium phthalocyanine complex are also reported here for the first time.
