3He NMR spectroscopy has been used to study the equilibria of Diels-Alder additions of 9,10-dimethyl anthracene (DMA) to (3)He@C(60) and (3)He@C(70). Spectra of a series of equilibrium mixtures showed peaks for the isomeric adducts. One monoadduct, s

Unimolecular decompositions of noble gas containing endohedral fullerenes as well as metallofullerenes were studied using tandem mass spectrometry techniques. Endohedral fullerenes do not lose the endohedral atom unimolecularly but fragment via the l

The fragmentation patterns resulting from collisions between (Ar@C 60 ) + or (Ar@C 60 ) − ions and H 2 , He, CH 4 , Ne, Ar and Kr target gases have been measured. The ion-source material Ar@C 60 was synthesized by heating C 60 under 3000 atm of arg

Bis- to hexakisadducts of C60 (1–6) and mono- to tetrakisadducts of C70 (7–13) containing 3He atoms (endo-hedral helium complexes) were prepared and studied by 3He NMR spectroscopy to determine the influence of degree of functionalization and add

Noble gas atoms can be introduced into the interior of fullerene molecules. A procedure, using a mass spectrometer system, is described for measuring the rates and amounts of noble gas released on heating these compounds. We find that the half life f

The high-pressure, high-temperature {sup 3}He labeling procedure previously used with C{sub 60} and C{sub 70} was applied to mixtures of isomers of the higher fullerenes C{sub 76}, C{sub 78}, and C{sub 84}. Sufficient helium was introduced inside the
