We present an analysis of a system of weakly coupled Hubbard chains based on combining an exact study of spectral functions of the uncoupled chain system by means of the pseudofermion dynamical theory with a renormalization group method for the coupled chains. Our theoretical predictions are consistent with the phase diagram observed in the (TMTTF)2X and (TMTSF)2X series of organic compounds.
