We present: high-resolution absorption spectral measurements of the A(1)Pi -X-1 Sigma(+) band system of (CO)-C-13-O-16. These were recorded with the VUV Fourier transform spectrometer (VUV-FTS) installed on the DESIRS beamline at the SOLEIL synchrotron. This work includes revised term values that extend to higher J' values than previous measurements for most nu' levels and lower J' values for nu' = 0. We confirm previously observed perturbations of the rotational levels in greater detail and present evidence for new perturbations. The accuracy in the wavelength determination and term values is on average within 0.01 cm(-1) improving upon previous measurements.
