    • Aroca, R. F.; Clavijo Campos, Ernesto; Halls, M. D.; Schlegel, H. B. (American Chemical Society, 2000)
      The surface-enhanced Raman scattering (SERS) spectra for phthalimide (PIMH) vacuum evaporated, cast onto silver island films, and from colloidal silver are clearly identified with the formation of a phthalimide-silver ...
    • Campos Vallette, Marcelo; Saavedra, M. S.; Diaz, G. F.; Clavijo Campos, Ernesto; Martinez, Y.; Mendizábal Emaldía, Fernando; Costamagna, Juan; Canales, J. C.; Garcı́a-Ramos, J. V.; Sánchez Cortés, S. (2001)
      The FT-Raman spectra and surface-enhanced Raman scattering (SERS) on silver colloid of the azabipiridyl ligand and its Co(II), Ni(II) and Cu(II) complexes are reported. A resonance Raman (RR) study of the solids and a ...
    • Carrasco, E. A.F.; Campos Vallette, Marcelo; Saavedra, M. S.; Díaz Fleming, Guillermo; Clavijo Campos, Ernesto; García-Ramos, J. V.; Sánchez Cortés, S. (2001)
      Infrared (middle and far) and Raman spectroscopy were used to study the adsorption of vanadylnaphthalocyanine and vanadylporphine tetraphenyl substituted macrocycles adsorbed onto metallic surfaces. The IR spectra of the ...
    • Campos Vallette, Marcelo; Clavijo Campos, Ernesto; Costamagna, Juan; Canales, J.; Díaz Fleming, Guillermo; Mendizábal Emaldía, Fernando; Ramirez, J. M.; Saavedra, M. S. (Elsevier, 2000)
      The infrared spectra of the azabipiridyl macrocycle complexes of Ni(II), Cu(II) and Zn(II) were registered between 4000 and 200 cm-1. The spectral assignment allowed to identify the complex formation and structural differences ...
    • Clavijo Campos, Ernesto; Campos Vallette, Marcelo; Saavedra, S. M.; Alvarado, A.; Díaz Fleming, Guillermo (1997)
      The FT-IR and Raman spectra for the solid naphthalocyanine (H2Nc) and their Co(II), VO2+ and Pb(II) complexes were registered, and a band assignment was proposed. On this basis, the structure of the complexes was inferred: ...
    • Carrasco-Flores, E. A.; Clavijo Campos, Ernesto; Campos Vallette, Marcelo; Aroca, R. F. (2004)
      The present report on the vibrational spectra of 1-nitropyrene (1-NP) describes the infrared and Raman spectra; their interpretation is aided by local density functional theory (DFT) calculations at the B3LYP/6-311G(d,p) ...
    • Clavijo Campos, Ernesto; Weiss López, Boris; Rivera, L. Patricio (1996)
      FT-IR and FT-Raman spectra of Caulerpin, a green algae pigment, have been recorded. An assignment of the observed bands is proposed on the basis of previously reported vibrational spectra of similar structures. Intensity ...
    • Saavedra, M.; Campos Vallette, Marcelo; Clavijo Campos, Ernesto; Mendizábal Emaldía, Fernando; Díaz, G.; García-Ramos, J. V.; Sánchez-Cortés, S. (2003)
      Fourier 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-boronnapht ...
