heal.abstract	We have carried out an extensive micro-Raman study on Mg(B1-xCx)(2) single crystals, for carbon concentrations up to x = 0.15. The E-2g symmetry broad band for pure MgB2 at similar to 600 cm(-1) disappears even for small doping levels (x = 0.027) and two well-defined peaks in the high-energy side of this band play a major role in the Raman spectra of the substituted compounds. We propose that a two-mode behavior of the compound might be present, induced by the coupling of the observed phonons with the electronic bands. (c) 2006 Elsevier B.V. All rights reserved.	en
