title: Extremely slow charge fluctuations in the metallic state of the two-dimensional molecular conductor theta-(BEDT-TTF)2RbZn(SCN)4.
abstract: Large charge disproportionation has been confirmed in the metallic state of a 1/4-filled organic conductor theta-(BEDT-TTF)2RbZn(SCN)4 by means of 13C-NMR analysis on a selectively 13C-enriched single crystal sample. By comparing the homogeneous and inhomogeneous linewidths, the temperature dependence of the extremely slow dynamics of charge fluctuations has been determined first. The exotic nature of the metallic state of this salt is discussed.
