Pfeiffer, R. (Kuzmany, Vienna, Austria): Concentration, symmetry and charcter of C60 in C60 peapods
Raman of peapods. Relative concentrations easy, absolute difficult
Found strong hybridisation and quasi-free rotation of the C60
Also polarized Raman. (Differentiate between parallel an perpendicular modes.)
Zerbetto calc: minimum SWNT diameter for C60 1.2 nm. Means C60-SWNT distance smaller than those betwen graphene layers.
