Abstract
The reflectance spectra of [SMe3][Ni(dmit)(2) (dmit=1,3-dithiole-2 thione-4 ,5-dithiolato), quarter-filled organic conductor with strongly dimerized st ructure, will be discussed in the framework of the new Raman results for th is compound. The spectra are interpreted on the basis of a dimerized Hubbar d octamer model, which accounts for the low energy electronic transitions a nd for the coupling of the electronic excitations with the intramolecular v ibrations.
