The Laboratory Determination of Relative Transition Probabilities of Diatomic Molecules. I. The a-SYSTEM of TiO

An electric furnace and a photoelectric spectrum-scanning technique were used to produce the intensity distribution-curve in the spectrum of the a-system of TiO from 4500 to 6200 A. The relative intensities of individual bands of the system were determined by matching their observed profiles with profiles determined theoretically. The resulting relative transition probabilities are presented in Table 1.
