Abstract
The rotational spectrum of 2-fluoropyridine has been analyzed in the region between 7 - 40 GHz. The rotational constants for the vibrational ground state are: A = 5870.90 MHz, 5 = 2699.96 MHz, C = 1849.26 MHz. The small inertia defect indicates that the nuclear frame is planar. The two components of the electric dipole moment were obtained from Stark effect measurements: μa = 2.80 ± 0.06 D, μb = 1.87 ± 0.05 D. These values agree well with an INDO closed molecular orbital calculation done at T.I.F.R. From the hyperfine splittings of the rotational line the 14N nuclear quadrupole coupling constant are determined. The values are :
Χaa=-0.02±0.05 MHz, Xbb = -2.80±0.05 MHz, Xcc = +2.82±0.05 MHz
