 Title: CHIRPED-PULSED FTMW SPECTRUM OF 4-FLUOROBENZYL ALCOHOL. STRUCTURE AND TORSIONAL MOTIONS IN THE GROUND ELECTRONIC STATE PHASE Creators: Bird, Ryan G.; Pratt, David W.; Neill, Justin L.; Pate, Brooks H. Issue Date: 2010 Publisher: Ohio State University Abstract: Previous studies of 4-fluorobenzyl alcohol (4FBA) in the gas phase have revealed the existence of tunneling splittings in its high resolution electronic spectrum. These could be attributed either to the ground $S_{0}$ state, or the excited $S_{1}$ state, or both. Motivated by this finding, we report here a study of the CP-FTMW spectrum of 4FBA. Its pure rotational spectrum was collected using a series of 250 MHz chirped pulses, over the frequency range of 6.5-18 GHz. Analysis of this data shows that 4FBA has a gauche structure and yields the \textit{V}$_{2}$ barrier for ??CH$_{2}$OH torsion, from which the predicted tunneling splittings in the ground state have been extracted.
