Abstract:
A consistent set of spectroscopic constants for the a1Δ,
d1Σ+, b1Π, c1Φ, and f1Δ states of
48Ti16O has been determined from analysis of the
b1Π-a1Δ, b1Π-d1Σ+, c1Φ-a1Δ,
and f1Δ-a1Δ systems. Three Fourier transform emission
spectra have been used for the analysis. New bands of the
b1Π-a1Δ and c1Φ-a1Δ systems have been
fitted. The first analysis of the c1Φ-a1Δ system using
Fourier transform spectra is also provided. Extensive and improved
line positions are measured. TiO is prominent in the spectra of
oxygen-rich cool stellar objects and may be present in hot-Jupiter
exoplanet atmospheres.
Description:
Three emission spectra have been used for the analysis of TiO reported
in this paper. The spectra were measured with the 1m Fourier transform
interferometer associated with the McMath-Pierce Solar Telescope of
the National Solar Observatory at Kitt Peak.
The first spectrum was measured on 1977 June 29 (770629R0.001);
spectral resolution of 0.044cm-1.
The second spectrum was also measured on 1977 June 29 (770629R0.005);
spectral resolution of 0.015cm-1.
The third spectrum was measured on 1985 January 19 (850116R0.002);
spectral resolution of 0.044cm-1.

Note (2): M1 in the presence of static field, otherwise J1 in the absence
of hyperfine structure, otherwise F1.
Note (3): This gives the index (starting from 1) of the upper|lower energy
level with respect to other levels of the same total angular
momentum and symmetry.
Note (4): M0 in the presence of static field, otherwise J0 in the absence
of hyperfine structure, otherwise F0.
Note (5): Such as P(1). The display will depend on the molecule type and the
electronic and nuclear angular momenta included in the calculation.
Note (6): Including other (possibly approximate) quantum numbers where
appropriate. The assignment process will also add the source of
the measurement (typically a filename) where possible.
