Abstract
The microwave spectra of three isotopomers of fluorobenzene-neon (normal, $^{22}Ne$ and $d-5$) have been observed using a Fourier transform spectrometer. Twenty-two transitions were fit to eight constants. The dimer has a stacked structure with the neon over the fluorobenzene ring in the symmetry plane. The center of mass distance $(R_{m})$ is 3.44(1) {\AA}, with the neon sitting between the center of mass and the center of the ring. The rotational constants have been determined as A = 1926.421(2) MHz, B = 1645.236(3) MHz, and C = 1279.734(1) MHz. The electric dipole moment was measured to be $|\mu_{a}| = 1.15(3) D. |\mu_{b}| = 1.12(3) D. |\mu_{t}| = 1.61(5) D$.
