摘要：
Measurement of relative band strengths of 10 absorption bands of the E-1 Pi(u)-X-g(1 Sigma)+ system of diatomic silver, Ag-107,109(2), was performed for the first time. Theoretical analysis of the experimental data, based on Rydberg-Klein-Rees potential energy curves, revealed that assumption of the r-centroid approximation is valid for this system. Comparison of the measured and computed band strength ratios for 5 pairs of bands having common lower levels led to the following linear relative electronic transition moment function for the Ag-107,109(2) E-X band system: R-e((r) over bar (v'v '')) = 2.36 (r) over bar (v'v '') - 5.64, in arbitrary units, over the 2.65-2.73 of internuclear distance.
