Triplet excitation of C 60 and the structure of the crystal at 1.2 K
Electron-spin-echo experiments at 95 GHz and 1.2 K reveal that the triplet excitation of a single crystal of C 60 is delocalized over either a pair or a chain of C 60 molecules along 〈110〉 directions. Two distinct triplet species have been observed in a one-to-one ratio which verifies the proposed 2...

Summary: | Electron-spin-echo experiments at 95 GHz and 1.2 K reveal that the triplet excitation of a single crystal of C
60 is delocalized over either a pair or a chain of C
60 molecules along 〈110〉 directions. Two distinct triplet species have been observed in a one-to-one ratio which verifies the proposed 2
a
0 face-centred cubic superstructure of the crystal at low temperature. The C
60 molecules on the two sublattices differ by a rotation over 60° about 〈111〉 directions. |
