Abstract

The pure rotational spectrum of FeO⁺ (X ⁶Σ ⁺) has been recorded using millimeter/submillimeter velocity modulation techniques, the first high-resolution measurement of a metal oxide cation. FeO⁺ was created in an AC discharge from Fe(CO)₅ and N₂O. Nine rotational transitions were recorded in the range 299-544 GHz, each consisting of six fine-structure components. The data were analyzed with a case (b) Hamiltonian, and rotational and spin parameters determined. The spin-spin constant suggests a low-lying ⁴Σ ^- excited state. The bond length established for FeO⁺, r₀ = 1.641, is slightly longer than that of FeO, consistent with a covalent bonding scheme.
