Laser desorption mass spectra of thin films of pure C60O were recorded in a range of equilibrium sample temperatures from 300 to 1100 K. On heating of the sample above 650 K a new peak corresponding to C119 is detected in the anion mass spectrum which persists even after the sample is cooled to 300 K. Possible solid state reactions leading to the formation of C119 are discussed based on the mass spectrometric observations as well as temperature programmed decomposition measurements which were carried out for C60 and C60O samples. The results are discussed in connection with recently reported polymerization reactions of fullerene materials.

S. Frank and T. P. Martin, personal communication. Laser desorption of a C60 pellet by 532 nm and postionization with 193 nm showed the presence of C119+ in addition to even numbered carbon clusters in the same size range.

The optical penetration depth α−1, where the incident intensity is attenuated a factor e −1, was determined by absorption measurements on vaccum sublimed C60 films on quartz substrates.
