Can optical spectroscopy directly elucidate the ground state of C20? [PDF]

, 2001
The optical response of the lowest energy members of the C20 family is calculated using time-dependent density functional theory within a real-space, real-time scheme. Significant differences are found among the spectra of the different isomers, and thus
