Abstract
The pure rotational spectrum of a minor isotopologue of ytterbium fluoride, 171YbF, in the X2Σ+ (v = 0) state has been recorded using Fourier transform microwave (FTMW) spectroscopy and pump/probe microwave optical double resonance (PPMODR) spectroscopy. The pure rotational spectra and precisely measured splittings in the (0, 0) A 2Π1/2 ← X2Σ+ band were analyzed to produce an improved set of fine and magnetic hyperfine parameters for the X2Σ+ (v = 0) state of 171YbF. A comparison with theoretical predictions is made. © 2014 Elsevier Inc. All rights reserved.
