“…In addition to previously reported transitions (14) (18) and their ⍀-assignments are consistent with the results of MCD matrix isolation experiments (19). A rotational analysis of a number of bands of these transitions has been carried out and molecular constants for the H (11) and r 0 ϭ 1.68519 7 Å for NbO (13).…”

The emission spectrum of TaO, excited in a tantalum hollow cathode lamp, has been observed at high resolution using a Fourier transform spectrometer. In addition to previously known transitions, a number of new bands have been identified and assigned as belonging to two new electronic transitions: H2Pi1/2-X2Delta3/2 and K2Phi5/2-X2Delta3/2. A rotational analysis ofthe 0-0 and 0-1 bands of the H2Pi1/2-X2Delta3/2 transition and of the 0-1, 1-2, 0-0, 1-0, and 2-1 bands of theK2Phi5/2-X2Delta3/2 transition has been carried out, providing the following equilibrium constants for the ground X2Delta3/2 state:omegae = 1028.9060(15) cm-1, omegaexe = 3.58928(66) cm-1, Be = 0.40289737(139) cm-1, alphae = 0.00185445(83) cm-1, andre = 1.6873430(29) Å. The principal molecular constants for the H2Pi1/2 state are T00 = 20 634.32758 (40) cm-1,B0 = 0.3766867(31) cm-1, and r0 = 1.7450604(72) Å, while the equilibrium constants for the K2Phi5/2 state areomegae = 905.4549(15) cm-1, omegaexe = 3.67601(64) cm-1, Be = 0.37965102(36) cm-1, alphae = 0.00189370(21) cm-1, andre = 1.7382343(8) Å. Although the H2Pi1/2 and K2Phi5/2 states have been observed previously in matrix isolation experiments, our work on these states is the first in the gas phase. Copyright 1998 Academic Press.

An accurate line list, VOMYT, of spectroscopic transitions is presented for hot VO. The 13 lowest electronic states are considered. Curves and couplings are based on initial ab initio electronic structure calculations and then tuned using available experimental data. Dipole moment curves, used to obtain transition intensities, are computed using high levels of theory (e.g. MRCI/aug-cc-pVQZ using state-specific or minimal-state CAS for dipole moments). This line list contains over 277 million transitions between almost 640,000 energy levels. It covers the wavelengths longer than 0.29 µm and includes all transitions from energy levels within the lowest nine electronic states which have energies less than 20,000 cm −1 to upper states within the lowest 13 electronic states which have energies below 50,000 cm −1 . The line lists give significantly increased absorption at infrared wavelengths compared to currently available VO line lists. The full line lists is made available in electronic form via the CDS database and at www.exomol.com.
