Molecular constants of (0, 0) and (1, 0) bands of C2 are obtained for the Hamiltonian formalism proposed by Zare et al. [J. Mol. Spectrosc. 46 (1973) 37]. Both a conversion method from molecular constants of Brown's Hamiltonian formalism and a nonlinear least-square-fit method are applied. The calculated rotational lines match the results of experiment within the range of 0.06-0.001 cm-1. Using these molecular constants, the spectrum of degenerate four wave mixing for (0, 0) and (1, 0) bands of C2 is calculated at 3000 K for a line-shape function of a Lorentzian cubed profile.
