β¦ Synopsis
The splitting of the 2t7g state of BeFz into the 2 B2 and 2A, components h.xs been inw&igated theoretically by ab initio UHF calculations. The 2A2 component is found to be linear, and the 2B2 state is calculated to ha% minima at bond an@% of 180Β° and = 100Β° _ with the bent conformation lying lower_ Analysis of a possible interaction between two states of 2B2 symmetry is made. Electron binding energies and symmetric bending force constants are reported. For comparisxt,a parallel investigation is reported on the analogous states of the isoelectronic CO:.

The potential energy curvesalong the bending motion for the \*AZ ((la\*)-'), \*B2 ((4b$') and \*B2 ((3bz)-') states of BeF: have been calculated by means of the EOM/propagator method. The 2B2 (( 3b,)-') curve, which was not obtained in previous UHF calculations because of variational collapse, shows
A variational approach is applied to calculate the vibronic energy levels and the corresponding wavefunctions for the \(X^{2} I_{u}\) electronic state of \(\mathrm{B}_{2} \mathrm{H}_{2}^{+}\). The potential surfaces involving variations of the symmetric B-H stretching, B-B stretching, trans- and cis
The 5 1 0 and 5 1 1 bands of the CaCCH A Λ2P-X Λ2S / transition, corresponding to the Ca-C-C bending mode, have been rotationally analyzed through cw dye laser excitation and dispersed fluorescence with a CCD array detector. The upper state is subject to Renner-Teller and spin-orbit couplings, and s
