The EPR method has been used to investigate thermal depolymerization processes of the tetragonal (T) and rhombohedral (R) 2D-polymerized phases of C60 in vacuum and in air. The behavior of paramagnetic centers (PCs) with doublet (S = 1/2) and triplet (S = 1) states during thermal depolymerization of the T and R phases have been analyzed and compared with the behavior of PCs of the monomer C60 phase at temperatures up to 650 K. A complete destruction of the PCs with triplet state on heating in the T and R phases has been observed. The EPR study of the monomer C60 phase shows the appearance of new PCs with triplet state in the 580–650 K temperature range. [ABSTRACT FROM AUTHOR] |
