Properties of the excited states of endohedral metallofullerenes (La@C-82 a
nd La-2@C-80) have been investigated by time-resolved absorption spectrosco
py. Transient absorption bands of La@C-82, showed two decay-components, whi
ch were attributed to excited states of different spin multiplicity. The pr
operties of photoexcited states of La-2@C-80 are also reported.
