The Spectrum of AgD

Abstract

The spectrum of AgD has been photographed at high dispersion with an Ag arc in an atmosphere of deuterium as a source. Quantum analyses of the 0,0 and 1,1 bands are presented. The value ${\beta }_e=3.2595\mathrm{}$ is found for the lower state. Comparing this with the corresponding value for AgH, the ratio $\frac{{B_e}^i}{B_e}$ for the two isotopic molecules is 0.50511, whereas the ratio of the reduced masses, by using Aston's latest values for the masses of the H and D atoms, is 0.50497. Calculation of the corrections to $B_e$ for the anharmonic oscillator as given by J. L. Dunham shows them to affect the $B_e$ ratio inappreciably.
