dc.description.abstractThe Magnetic vibrational circular dichorism spectra (MVCD) of C$60$ fullerene in solution will be presented for $t_{1u}$-symmetry fundamental vibrations at 1430 and $1183 cm^{-1}$. Two MVCD A-terms of opposite sign $(A_{1}/D_{0} = -3.8$ and $1.1 \times 10^{-4}$, respectively) which are similar in magnitude to that of benzene are $observed.^{1}$ According to the single excited-state vibronic coupling model and using the two lowest-energy $^{1}T_{1u}$ excited electronic states, the sign of one of the MVCD bands is correctly predicted while the magnitudes of both bands are underestimated. Recent theoretical predictions for the electronic MCD of $C_{60}$ based on extended Cl calculations at the CNDO level predict oppositely signed MCD A-terms for the two low energy $^{1}A_{g}$ to $^{1}T_{1u}$ electronic $transitions.^{2}$ If correct, these variations could explain the observed C$60$ MVCD sign patterns.en_US
