Electron spin relaxation of N@C60 in CS2

“…A fit to the data in Figure 4 yields ∆ = 32(1) meV. This is a close match to the energy of the first vibrational mode of C 60 (273 cm −1 , or 34 meV) which has been theoretically calculated and observed by Raman spectroscopy of C 60 in CS 2 solution at 300K [18,19,20], indicating that this may be a vibrational spin-orbit Orbach process [21,22]. This first excited vibrational mode, termed H g (1), breaks the spherical symmetry of the molecule, reducing it to axial.…”

The infrared spectra of nonplanar polycyclic aromatic hydrocarbons with five- or seven-membered rings

“…However, some experiments have significantly more bands than the allowed fundamentals, while others report only a subset of the allowed bands. We picked three sets of experimental IR and Raman data [36][37][38] to compare our computed bands with. (N.b.…”

Discrete Fulleride Anions and Fullerenium Cations

“…[254][255][256][257][258] These are the T u (1-4) modes at 527, 576, 1183, and 1429 cm -1 . The response of these frequencies to the addition of charge and Jahn-Teller lowering of symmetry are of considerable interest.…”

“…255,257,258,267,268 These have been intensively studied in A x C 60 intercalated compounds because of interest in their involvement in an electron-phonon coupling mechanism for superconductivity in A 3 C 60 . 269,270 It was quickly discovered that the A g "pentagonal pinch" mode at 1467 cm -1 was a good indicator of charge state in intercalated compounds.…”
