    • Olea Azar, Claudio; Rigol Olsen, Carolina; Mendizábal Emaldía, Fernando; Briones, Rodolfo (BENTHAM SCIENCE PUBL LTD, 2006-02)
      Free radicals may be reaction intermediates in biological systems in more situations than are presently recognized. However, progress in detecting such species by Electron Spin Resonance (ESR) has been relatively slow. ESR ...
    • Olea Azar, Claudio; Rigol Olsen, Carolina; Mendizábal Emaldía, Fernando; Briones, Rodolfo; Cerecetto, Hugo; Di Maio, R.; Risso, Mariela; González, M.; Porcal, Williams (PERGAMON-ELSEVIER SCIENCE LTD, 2003-01-01)
      The electron spin resonance (ESR) spectra of free radicals obtained by electrolytic or microsomal reduction of several potential antiprotozoal 1,2,5-oxadiazoles were characterized and analyzed. Ab initio molecular orbital ...
    • Olea Azar, Claudio; Mendizábal Emaldía, Fernando; Alarcón, Jaime; Briones, Rodolfo; Cassels Niven, Bruce; Delgado Castro, Tomás; Araya Maturana, Ramiro (PERGAMON-ELSEVIER SCIENCE LTD, 2001-08)
      The ESR spectra of radicals obtained by electrolytic reduction of 4,4-dimethylanthracene- 1,9,10 (4H)-trione (1) and the regioisomeric quinones 8-acetyloxymethyl-4,4,5-trimethyl- (2), and 5-acetyloxy-methyl-4,4,8-trimeth ...
    • Mendizábal Emaldía, Fernando; Olea Azar, Claudio; Briones, Rodolfo (JOHN WILEY & SONS INC, 2001-04-15)
      Electronic structure aspects related to the semiconducting properties of monomers and polymers of phythalocyanoiron with bidentate bridging ligands, PcFe-L-2 and -[PcFe(L)](n), have been investigated from density functional ...
    • Rigol Olsen, Carolina; Olea Azar, Claudio; Mendizábal Emaldía, Fernando; Briones, Rodolfo; Cerecetto, Hugo; González, M. (ELSEVIER SCIENCE BV, 2006-09-29)
      Theoretical studies of molecular conformations and electronic properties calculations of eight 5-nitrofuryl thiosemicarbazone free radicals, by means of ab initio (R/UHF), and DFT (R/UB3LYP) methods are presented and ...
    • Mendizábal Emaldía, Fernando; Olea Azar, Claudio; Briones, Rodolfo (ELSEVIER SCIENCE BV, 2006-05-30)
      The electronic structure and the spectroscopic properties of [M(CN)(2)](n)(-n), (M = Au(I), Ag(I); n = 1-3) were studied using density functional theory (DFT) at the B3LYP level. The absorption spectrums in these complexes ...
