We measured the transmission between 1.6-2.2 eV of pure C60 and three clathrate single crystals containing different aliphatic guest molecules. The absorption edge in the clathrates shows a blue shift of 0.1 eV irrespective of the guest molecule, indicating that C60 is electronically isolated in these compounds.
