Abstract
We report on dc and microwave experiments on the quasi one-dimensional organic conductor (TMTSF) ₂PF ₆ along the a, b' and $c^{\ast }$ directions. In the normal state below 70 K, the dc resistivity follows a power-law $\rho _{\rm a}$ , $\rho _{\rm b} \propto T^{ 2}$ and $\rho _{\rm c} \propto \quad T$ . Above T = 100 K the exponents extracted from the data (transformed to constant volume conditions) in the longitudinal and transverse directions do not form a picture which is consistent with the predictions by the Luttinger liquid model. The contactless microwave measurements of single crystals along the b' axis reveal an anomaly between 25 and 55 K which is not understood yet. Key words. one-dimensional organic conductors - transport properties - Fermi liquid - Luttinger liquid.
