We present the photoelectron spectrum of CsO−, recorded using 2.540 eV photons. This spectrum provides a direct measurement of the X 2Σ+–A 2Π energy splitting in CsO, which is found to be 0.135±0.025 eV. This work also establishes that the ground state of CsO− is 1Σ+. In addition, the adiabatic electron affinity of CsO is found to be 0.273±0.012 eV, while the D0 value for the X 1Σ+ state of CsO− (with respect to Cs+O−) is found to be 1.84±0.15 eV. Molecular parameter estimates for CsO− are also extracted from the spectrum.
