The Red Titanium Oxide System in α_{1} Herculis

Sixty-six bands belonging to the red system of TiO have been measured in the spec- trum of a1 Herculis between A 6292 and X 8506. Of these, eleven bands of the sequence -2 have never been observed in the laboratory. The Q-heads in the star seem to be much fainter than in the laboratory sources. In addition to the bands in the red sys- tem, four bands belonging to the blue-green system of TiO and two unclassified bands of TiO have been found in the same spectral region in this star
