The ground state and zero-field splitting of the GdO molecule

Article abstract of DOI:10.1063/1.441970

The X-band ESR spectrum of GdO was obtained in an argon matrix at 4 K as a series of 16 fine-structure lines between 0 and 12 000 G.Analysis proved that most of these lines were due to off-principal-axis transitions and established the ground state as ⁹Σ.An accurate fit to the data required the inclusion of a smallb₄⁰ term (quartic in S_z) besides the usual b₂⁰ = D term in the spin Hamiltonian.The derived parameters in an argon matrix are g<*> = 1.990(9), g<*> = 1.986(5), 2⁰> = = 0.2078(3) cm^-1, and 4⁰> = 0.000 40(5) cm^-1.The two strongest lines were also observed in a neon matrix.
