Raman scattering of thin films, and surface enhanced $\{$resonance$\}$ Raman scattering (SE$\{$R$\}$RS), mostly of Langmuir-Blodgett (LB) monolayers are interpreted for various phthalocyanine derivatives. SERS and SERRS are reported for phthalocyanines transferred to silver and gold island films and silver coated tin spheres. The Raman data were complemented with the infrared (IR) data and the vibrational assignment of the phthalocyanine was attempted. The Raman spectra of vanadyl phthalocyanine sublimed as an ultra thin film onto reflecting surfaces are reported. Energy transfer and enhanced absorption was observed in a two component system composed of one LB of a perylene derivative and one LB of zinc tetra-tert-butylphthalocyanine. The LB technique was applied to control the coverage on the surface in the investigation of SERRS of vanadyl tetra-tert-butylphthalocyanine and surface coverage dependence. SERRS, IR, ultraviolet-visible (uv-vis) spectroscopy were used to characterize stable green and blue forms of lanthanide bisphthalocyanine complexes. SERRS was applied to investigate the interaction of nitrogen dioxide and one LB of metal-free tetra-tert-butylphthalocyanine, copper tetra-tert-butylphthalocyanine and ytterbium (and lutetium) bisphthalocyanines. UV-VIS spectroscopy was also valuable in the investigation of nitrogen dioxide and the phthalocyanine derivatives.Dept. of Chemistry and Biochemistry.
