A comprehensive investigation of the charge and spin dynamics of the quasi
one-dimensional organic compounds (TMTSF)(2)X and (TMTTF)(2)X with X = PF6,
AsF6, Br, and ClO4 has been performed in the temperature range from 2 K up
to 500 K. By substitution of the organic donors or inorganic anions, the d
imensionality of the systems can be tuned. While the resisitivity strongly
increases in (TMTTF)(2)X below 100 K! the susceptibility measured by electr
on spin resonance varies only slightly.
