J. Hutter, H.P. Luthi, and F. Diederich (J. Amer. Chem. Soc. 116,750 (1994)) examined the geometric and vibrational structure of several carbon molecules of formula Cn' Given that the ground state of C3, a molecule found in interstellar space and in flames, is an angular singlet with moments of inertia 39.340, 39.032, and 0.3082 u A2 (where 1 A= 10-10 m) and with vibrational wave numbers of 63.4, 1224.5, and 2040 cm-1, compute Gm (10.00K) - Gm (0) and Gm (1000K) - Gm (O)for C3
