Abstract
Surface-induced dissociation (STD) of purified La@C-82 on a fluorinated sel f-assembled monolayer (F-SAM) film has been studied by a reflectron-type ti me-of-flight mass spectrometer modified for measuring SID spectra. Lanthanu m-containing fragments LaCn+ formed as a result of sequential C-2-loss proc esses have been observed. No lanthanum-stripping fragmentation was observed , up to 160 eV collision energies. The SID of LaC60 on the F-SAM film has a lso been investigated up to 100 eV collision energies. The SID profiles of LaC60 are similar to those of La@C-82 which strongly suggests that La@C-60, like La@C-82, has an endohedral structure. (C) 1999 Elsevier Science B.V. All rights reserved.
