Abstract :
Ultraviolet photoelectron spectra (UPS) of three Tm@C82 isomers were measured with a synchrotron radiation light source. The upper valence band spectra (0–5 eV) of three isomers are different each other and they also differ from those of other trivalent metal atoms encapsulated metallofullerenes, such as La@C82, Sc@C82 and Gd@C82. Resemblance of the spectra of Tm@C82 (II) and Ca@C82 (III) suggests identical cage structures of these two metallofullerenes. The UPS are well reproduced by simulated spectra obtained with ab initio calculation, which indicates that isomers I–III have Cs (No. 4), C2 (No. 5) and C2v (No. 9) cage structures.
