Abstract
The $A^{2}\Sigma^{+} -X^{2}\Pi$ transition of AgO has been observed for the first time. The spectrum was observed at $8300 cm^{-1}$, recorded in emission with the high resolution, Fourier transform spectrometer associated with the McMath-Pierce Solar Telescope at Kitt Peak. The excited AgO molecules were produced in a low pressure silver hollow cathode, using a slow flow of 0.8 Torr neon and 15 mTorr oxygen, Preliminary constants for the $A^{2}\Sigma$ state of AgO are: $T_{0}=8294.7$ $cm^{-1}$ B=$0.332 cm^{-1}$, $\gamma=0.037$ $cm^{-1}$ Preliminary constants for the $X^{2}\Pi$ state of AgO are: $A_{so}=-269.9$ $cm^{-1}$ B=$0.309 cm^{-1}$, and p=-$0.022 cm^{-1}$. The silver isotope structure is resolved at high J ($^{107}$ Ag 52%, $^{109}$Ag 49%). The analysis of this transition will be presented.
