Abstract
The photoelectron spectrum of CrO- is reported, with four electron sta tes of CrO detected. The (5) Pi ground state of CrO has an electron af finity of 1.221 +/- 0.006 eV. An excited (3) Pi state is also observed , which lies 8600 +/- 40 cm(-1) above the ground state. Two additional states of CrO, believed to be triplets, are observed at energies of 4 835 +/- 80 and 7365 +/- 40 cm(-1), respectively.
