C70 Fullerene

The lesser known fullerene C70 was initially detected in the same observations as C60 buckyball by Cami and co-workers in 2010 using the Spitzer Space Telescope. C70 has proven to be more elusive than C60, which was found in various other sources in additional observations by Cami et al. while C70 went undetected. C70 was detected toward the Magellanic clouds by García-Hernández in 2011. Both C60 and C70 had previous been detected in the Allende meteorite by Becker and co-workers. The detections of fullerenes are based on vibrational features observed in the IR. Data is also available for the C+
70
and C
70
ions measured by Kern and co-workers and for protonated C70 measured by Palotás and co-workers.

C70 fullerene was not isolated and identified in a terrestrial lab until the work of Kroto and co-workers published in 1985.
