(Received 26 January 1987; accepted 6 March 1987) We have measured 132 transitions in the ν³ (CN stretching) fundamental and the corresponding bending and stretching hotbands of the cyanate anion, ranging from P(52) to R(66), with a tunable diode laser using the velocity modulation technique.The spectra were fit to the standard linear triatomic molecule rotation-vibration Hamiltonian, yielding efiective molecular parameters for the (00⁰0), (O1¹0), (02⁰0), ( 1O⁰O), (00⁰1 ), (O1¹1), (02⁰1 ), and ( 10⁰1 ) states.The equilibrium rotational constant was determined to be B_e = 0.385 933 ( 116) cm^-1.A comparison with condensed phase results is presented.As previously oberved for N₃^- 3, cyanate is detected with high vibrational excitation in the bending mode, most likely as a consequence of the formation mechanism.
