The Quantum Analysis of the Band Spectrum of Aluminum Oxide (λ5200−λ4650)

Abstract

Frequencies of lines in band spectrum of AlO.—The spectrograms were taken by R. T. Birge, using a new form of aluminum arc of his design. A table of frequencies of all measured lines is given, extending over ranges of 135, 70 and 65 lines of both branches of the (0,0), (0,1) and (1,0) bands respectively. No perturbations were observed within the range of measurement. Complete numerical formulas expressing the frequencies of all individual band lines within the range of measurement are given. The doublet separations are found to agree in bands of the same final vibration state. Numerical formulas for the doublet separation are given, in which the coefficients are consistent with the theory applied to the mean of doublet components.
