| Sumario: | The colloidal solution of fullerene C60 in water has been investigated by UV-VIS
spectroscopy. It is shown that the peculiarities of colloidal solution spectrum are similar to
UV-VIS spectrum for solid state C60. The direct and indirect optical transitions were found for
this colloidal solution of fullerene. The existence of indirect transitions proves the presence of
solid state C60 in water. The influence of IR laser irradiation on the colloidal solution of
fullerene in water was also investigated. It is shown that under action of high power laser
radiation the red shift of the optical line corresponding to hu↔t1u (HOMO-LUMO) transitions
arises. Other transitions are not affected by IR laser. |
