New Assignments in the 600 nm Region of C60: The Origins of the T1g and Gg Transitions

We show that recent fluorescence and fluorescence excitation spectra of C 60 can be combined with earlier theoretical and experimental results to locate the origins of the two lowest single excited states, namely, S 1 (T 1g ) and S 2 (G g ). At the same time, we assign all the prominent features of fluorescence and fluorescence excitation spectra.
