N2 - High-accuracy dispersive optical spectroscopy measurements in the visible (VIS) region have been performed on the less-abundant (CO)-C-12-O-17 isotopologue, observing high-resolution emission bands of the B-1 Sigma(+) (nu = 0) -> A(1) II (nu = 3, 4, and 5) Angstrom system. These are combined with high-resolution photoabsorption measurements of the (CO)-C-12-O-17 B-1 Sigma(+) (nu = 0) X-1 Sigma(+) (nu = 0) and C-1 Sigma(+) (nu = 0)) X-1 Sigma(+) (nu = 0) Hopfield-Birge bands recorded with the vacuum-ultraviolet (VUV) Fourier transform spectrometer, installed on the DESIRS beamline at the SOLEIL synchrotron. The frequencies of 429 observed transitions have been determined in the 15 100-18 400 cm(-1) and 86 900-92 100 cm(-1) regions with an absolute accuracy of up to 0.003 cm(-1) and 0.005 cm(-1) for the B-A, and B-X, C-X systems, respectively. These new experimental data were combined with data from the previously analysed C -> A and B -> A systems. The comprehensive data set, 982 spectral lines belonging to 12 bands, was included in a deperturbation analysis of the A(1)II, nu = 1-5 levels of (CO)-C-12-O-17, taking into account interactions with levels in the d(3) Delta(i), e(3)Sigma(-), a(,3)Sigma(+), I-1 Sigma-and D-1 Delta states. The A(1) II and perturber states were described in terms of a set of deperturbed molecular constants, spin-orbit and L-uncoupling interaction parameters, equilibrium constants, 309 term values, as well as isotopologue-independent spin-orbit and rotation-electronic perturbation parameters.
