The phases of quenched fullerenes RbC60

RbC60 is known to exist in several stable phases as a function of temperatu re. Particularly interesting system warmed up from a quenched low temperatu re cubic phase. Subsequently, a dimeric, a monomeric and a polymeric phase are obtained and were analysed by Raman spectroscopy. The dimeric phase is of particular interest, since it exhibits a degenerated H, modes and an unu sual but very well expressed lack of any splitting for the G, modes. This a ll of the spectra to those of C-60.
