✦ Synopsis

By means of a purely quantum mechanical method, we construct an accurate potential energy function for the (X^{\prime} \Sigma^{+})ground electronic state of (\mathrm{CO}) from a large set of experimental frequency data for vibration-rotational bands of several isotopic species. We use an analytical expression for the potential in the form of a Dunham series for the Born-Oppenheimer part plus massdependent corrections. A total of 19 parameters are necessary in order to represent the potential energy function capable of reproducing with good accuracy the set of more than 10000 highquality transition frequencies.

The potential energy surface for the electronic ground state of CO 2 is refined by means of a two-step variational procedure using the exact rovibrational Hamiltonian in the bond length-bond angle coordinates. In the refinement, the observed rovibrational energy levels for J = 0-4 below 16,000 cm -1

We report new potential energy curves for the X 1 + and A 1 states of the CO molecule by employing the realistic extended Hartree-Fock approximate correlation energy model for diatomics with inclusion of the united-atom limit (EHFACE2U). Special care has been taken to describe the A 1 potential maxi

In this paper a new spectroscopic investigation on the X 1 ⌺ ϩ electronic ground state of the RbCs molecule is reported. This study is conducted by using laser-induced fluorescence combined with Fourier transform spectroscopy (LIF-FTS). More than 23 000 spectral data are used in a global linear redu

The ground state X 1 S / of the diatomic molecule KLi has been studied by analyzing spectra of the B 1 P-X 1 S / system, simplified by polarization labeling. Rotational and vibrational constants are reported for the X 1 S / state covering about 45% of its potential well depth and the potential curve

The results from the separate analyses demonstrate clearly that the two hamiltonian operators are essentially equivalent, both achieving equally satisfactory representations of the spectral data, and furnishing virtually identical Born-Oppenheimer potential functions. Fully quantum-mechanical vibrat
