Diaz, G. F.; Clavijo Campos, Ernesto; Campos Vallette, Marcelo; Saavedra, M. S.; Diez, S.; Muñoz, R. (1997)An infrared study of the macrocycles cyclam, cyclamdione and its Cu(II) complexes has been performed. The specular reflectance infrared spectrum was recorded and analyzed for the ligands and complexes deposited onto a ...

Díaz Fleming, Guillermo; Campos Vallette, Marcelo; Saavedra, M. S.; Clavijo Campos, Ernesto; Canales, J. C.; Costamagna, J.; Vargas, J. (Elsevier, 2002)A complete assignment of the infrared spectra of the title macrocycles was carried out on the basis of well-documented references and a normal coordinate analysis based on a simplified molecular model. The structure of the ...

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 ...

Olave, C. R.; Carrasco, E. A. F.; Campos Vallette, Marcelo; Saavedra, M. S.; Clavijo, R. E.; Figueroa, W.; Díaz Fleming, Guillermo; Sánchez Cortés, S.; Domingo, C.; Costamagna, J.; Ríos, A. (Elsevier, 2002)The FT-IR and Raman spectra in the solid state, the reflection-absorption IR spectra (RAIRS) and the surface enhanced IR (SEIR) and surface enhanced Raman spectra (SERS) of the Ni(II) (trans-7,14-dimethyl-5,12,-diphenyl- ...
