Raman scattering is used to study the filling of single wall carbon nanotubes with C 60 , C 59 N and anthracene. It is demonstrated how reversible opening and closing of the tubes can be used to check on the success of the filling process. In the case of C 59 N, filling was performed from the gas phase from 1:1 mixture between C 60 and C 59 N. Comparing the Raman spectra from the encapsulated mixture with the spectra from C 60 inside the tubes reveals that most of the molecules have reacted to form either the dimer (C 59 N) 2 or the hetero‐dimer C 60 C 59 N. Anthracene is demonstrated to enter the tubes but the molecule is subjected to a considerable geometrical change including some loss of hydrogens. Copyright © 2007 John Wiley & Sons, Ltd.
