The molecular Zeeman effect was observed in méthylène fluoride using a molecular beam maser spectrometer with the cavity in a 100-kG magnetic field. This combination of high fields and high resolution (4 kHz at 22 GHz) provides unusually high resolution for these measurements. The rotational transition 3os->2i2 at 22 204 240±2 kHz was observed in emission. The measured fluorine magnetic shielding anisotropies are 2σcc- σaabb=- 335.0±35 ppm and σaabb = 9.0±13 ppm. Accurate susceptibility anisotropies and molecular quadrupole moments were also obtained.
