Abstract:
Spectroscopic properties of SiO have been calculated from highly
correlated wave functions. The computed dipole moments for v=0-3 agree
well with the experimental data of Raymonda et al. (1970, J. Chem.
Phys. 52, 3458). By comparing the present results with previous
theoretical works, we estimate that the resulting line strengths
should be the most accurate to date. The Einstein coefficients for the
fundamental and the first overtone (v≤40, J≤100) are larger than the
currently used values of Tipping & Chackerian (1981, J. Mol. Spectr.
88, 352), and should be tested in models of stellar atmospheres.
