    • Surface vibrational study of macrocycle complexes: Co(II), Ni(II), Cu(II) and Zn(II) bis(phenylhydrazine) ... 
      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 ...
    • Surface-enhanced vibrational study of azabipiridyl and its Co(II), Ni(II) and Cu(II) complexes 
      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 ...
    • Vibrational study of N-phenyl-substituted hydroxynaphthylaldiminate copper(II) complexes 
      Campos Vallette, Marcelo; Figueroa, K.; Latorre, Ramón; Díaz Fleming, Guillermo; Costamagna, J.; Canales, J. C.; Rey-Lafon, M.; Derouault, J. (1993)
      The infrared spectra of seven bis(N-phenyl-substituted hydroxynaphthylaldiminate) complexes of Cu(II) were scanned from 4000 to 100 cm-1. Particular emphasis is given to the low-energy region. The assignment of the chelate ...
