dc.description.abstractRotational spectrum of the CoCO radical generated by ultraviolet photolysis of $Co(CO)_{3}NO$ was measured in the millimeter wave region to determine rotational and hyperfine interaction constants. Rotational transitions ranging from J = 29.5 - 28.5 to 34.5 - 33.5 were assigned in the $\Omega = 3/2$ and $\Omega = 5/2$ spin substates of the $X^{2}\Delta_{i}$ ground vibronic state as well as in the vibrationally excited states $\nu_{2}, \nu_{3}$, and $2\nu_{2}$ of the $\Omega = 5/2$ spin substate. Each rotational transition was split into 8 hyperfine components due to the $^{59}Co$ nucleus. Molecular constants, including the rotational constant B, centrifugal distortion constant D, nuclear spin-orbit interaction constant a, Fermi contact interaction constant $b_{F}$, magnetic dipolar interaction constant c, and nuclear quadrupole interaction constant eQq, were determined for the vibrationally ground state by least squares fitting of the observed spectrum. The equilibrium rotational constant $B_{e}$ was determined to be 4435.7510(18) MHz and the internuclear distance between Co and C was evaluated to be $1.688 \AA$. The a and c values are consistent with the values estimated from the hyperfine constants of the $^{59}Co$ atom. The $b_{F}$ value is nearly equal to zero.en_US
