N2 - The 28 absorption features in the 130-170 GHz spectral region have been measured and assigned as fine-structure components of 14 pure rotational transitions of calcium isocyanide (CaNC) in its (0, 0, 0) Χ 2Σ+ state. The spectrum was analyzed using a standard Hamiltonian model for a linear molecule, and the resulting spectroscopic parameters were used to predict the transition frequencies and Einstein A-coefficients. The determined parameters are (in MHz) B = 4040.742(14), D = 4.96(3) × 10-3 H = 4.1(3) × 10-7, L = -6.0(13) × 10-11, M = 5.3(20) × 10-15, γ = 18.03(12), γD = -3.2(13) × 10-5, where the numbers in parentheses are 3 σ error estimates.
