Infrared diode laser spectroscopy of the CCO radical : The 2 nu(1)-nu(1) and nu(1)+nu(3)-nu(3) difference bands
The 2 nu(1) - nu(1) and nu(1) + nu(3) - nu(3) difference bands of the CCO radical in the gas phase have been studied using a tunable infrared diode laser spectrometer. The CCO radical was produced using a flowing mixture of carbon suboxide and helium subjected to a hollow-cathode discharge. The spectral region between 1920-1960 cm(-1) was probed. Ninety and seventy-five rovibrational transitions were measured in the 2 nu(1) - nu(1) and nu(1) + nu(3) - nu(3) bands, respectively. The analyses of these bands yielded spectroscopic constants for the (001), (200), and (101) vibrational states. The band origins for 2 nu(1) - nu(1) and nu(1) + nu(3) - nu(3) determined to be 1941.85761(54) cm(-1) and 1936.79402(56) cm(-1), respectively.
