Ki. Pokhodnya et al., Optical excitations in a quarter-filled Ni(dmit)(2) based compound described by a dimerized octamer model, SYNTH METAL, 103(1-3), 1999, pp. 2187-2187
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.
