In addition , the MCD bands of La ( 2 ) @ I ( h ) - C ( 80 ) were altered upon [ 5 , 6 ] - addition , demonstrating that the MCD spectroscopy is sensitive to chemical functionalization of EMFs , and that it is therefore powerful to distinguish [ 5 , 6 ] - adducts from pristine La ( 2 ) @ I ( h ) - C ( 80 ) , although no marked difference exists in their absorption spectra .
 Chemical: La ( 2 ); Chemical: C ( 80 ); Chemical: La ( 2 ); Chemical: C ( 80 )
