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 Maa = -19.77 ± 0.21 kHz, Mbb = -13.46 ± 0.14 kHz, and Mcc = -7.80 ± 0.26 kHz. Magnetic shielding parameters are calculated from experimental results and comparison is made with other molecules.
