N2 - The pure rotational spectrum of the ScC2 radical (X̃2A1) has been measured using Fourier transform microwave/millimeter-wave techniques in the frequency range 15-63 GHz - the first high-resolution spectroscopic study of a 3d dicarbide species. ScC 2 was created in a supersonic expansion from laser-ablated scandium and CH4 in the presence of a DC discharge. Four transitions, N Ka,Kc = 101 → 000 through 404 → 303, were recorded, each consisting of multiple fine/hyperfine components; rotational, fine structure, and Sc(I = 7/2) hyperfine constants were determined. These measurements confirm the T-shaped geometry for ScC 2, and suggest the molecule has significant covalent character.
