Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obta
ined in a low-pressure are in oxygen atmosphere, and recorded with medium d
ispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system we
re verified by the study of the oxygen isotope effect, and the vibrational
constants were obtained for the states involved in transitions.
