✦ Synopsis

We have solved the nuclear Schrödinger radial equation to derive wavefunctions and rovibrational energy levels of the carbon monoxide molecule ({ }^{12} \mathrm{C}^{16} \mathrm{O}) in its ground electronic state (X^{\prime} \Sigma^{+}) at a spectroscopic accuracy. We then calculated the dipole matrix elements for transitions involving vibrational quantum numbers up to (v=15) and rotational quantum numbers up to (J=200). Calculations were carried out for the fundamental ((\Delta v=1)) and the three first overtone ((\Delta v=) (2,3,4) ) bands. For the transition matrix elements there is typically a (10 %) difference from previous results due to recent values of the dipole moment function. This gives a significant (20 %) difference for the absorption oscillator strengths which are computed for this set of 21600 lines. C 1993 Academic Press, Inc.
