Abstract
With a metallic strontium arc in a hydrogen atmosphere as a source, high dispersion spectrograms of three groups of bands in the near infrared with main heads at 7020A, 7347A and 7508A have been obtained. Analysis shows that the latter two groups of bands constitute a system with only the (0, 0) and (1, 1) vibrational transitions, while the first group represents a transition from a higher to the same normal state. Quantum analyses of the (0, 0) bands give for the normal state and , cm. For the state, , , , and . The rotational energy constants for the upper state are and . The spin doubling constant in the normal state is +0.122, in the upper state it is -3.81, while from the -type doubling in the state and . The doubling in the , band is much the largest yet found in bands of this type. From the near equality of the of the and the of the upper and their close agreement with calculated values, it is to be concluded that these two states stand to each other in the relation of "pure precession", as is the case for the corresponding states of CaH. The probable electron configurations are then and for the and upper states and for the normal state.
