Abstract

Hyperfine structure on the 1₁₀ → 1₁₁, 2₁₁ → 2₁₂, 4₃₁ → 4₃₂, and 6₅₁ → 6₅₂ rotational transitions in COF₂ was observed with a molecular beam maser spectrometer. The resonance line width (fwhm) ranged from 1.5 kHz on the 1₁₁ → 1₁₀ transition to 6 kHz on the highest frequency transitions. The diagonal elements of the spin-rotation tensor obtained are M_aa = -19.77 ± 0.21 kHz, M_bb = -13.46 ± 0.14 kHz, and M_cc = -7.80 ± 0.26 kHz. Magnetic shielding parameters are calculated from experimental results and comparison is made with other molecules.
