摘要：

High-resolution jet emission spectra of (CO)-C-12-O-18 in the 1380-1650 Angstrom region of the 4th positive bands, A (1) Pi --> X (1) Sigma(+), have been recorded photographically and have been reduced to upper-state term values for low to medium rotational quantum numbers in the 10 lowest vibrational levels of A (1) Pi. The deperturbation of the A state from spin-orbit and rotation-electronic interactions with singlet and triplet Sigma and Delta states has established the percentage (1) Pi character of the observed excited-state rovibronic levels. Dunham series expansion coefficients representing the deperturbed energies have also been determined.
