Description
The radical anion spectra of C-60 and C-70 can be easily generated and studied in primary aliphatic amines. In these conditions the C-60-center dot and C-70-center dot species are accompanied by the dianions C-60(2-) and C-70(2-). In the near infrared region the electronic transitions at 1075, 1058 and 991 nm were assigned to C-60-center dot while those at 1020-1030 nm and at 933 nm were assigned to the fullerene dianion C-60(2-). The electronic transition of C-70-center dot occurs at 1370 nm and that of C-60(2-) at 1170 nm, but in primary aliphatic amines C-70 also display a broad absorption band at 814-820 nm with other features certainly due to a specific interaction of the amine with C-70. The behavior of C-60 was studied with primary aromatic amines, but no interaction was found. Furthermore, solutions of C-60 and C-70 were studied with the secondary amine dioctylamine and with the tertiary amines triethylamine and N,N,N',N'-tetramethylethylenediamine (TMEDA). FT-IR spectra of selected fullerene-amine adducts were reported.

Low- to intermediate-mass (M < 8 solar masses, Ms) stars represent the majority of stars in the Cosmos. They finish their lives on the Asymptotic Giant Branch (AGB) - just before they form planetary nebulae (PNe) - where they experience complex nucleosynthetic and molecular processes. AGB stars are important contributors to the enrichment of the
