question

J.G. Dojahn, et al. (J. Phys. Chem. 100, 9649 (1996)) characterized the potential energy curves of the ground and electronic states of homonuclear diatomic halogen anions. The ground state of F2−\mathrm{F}_2^{-}is 2∑u+{ }^2 \sum_{\mathrm{u}}^{+}with a fundamental vibrational wavenumber of $450.0 \mathrm{~cm}^{-1}$ and equilibrium internuclear distance of 190.0pm190.0 \mathrm{pm}. The first two excited states are at 1.609 and 1.702eV1.702 \mathrm{eV} above the ground state. Compute the standard molar entropy of F2−\mathrm{F}_2^{-}at $298 \mathrm{~K}$.
