Yes, I saw that in C60 derivatives between a hydrogen just above the surface
and the other one in a C60-retinol A adduct.

Dear all,
It is well known that diastereotopic protons give differently shifted
signals in the 1H-NMR spectrum, but what about difference as great as 1 -
1.5 ppm? Do you think it is possible and has anyone ever observed such a
fenomenon?
