Title:GLOBAL FIT OF O-FLUOROTOLUENE TORSIONAL STATES FROM WAVEGUIDE CP-FTMW SPECTROSCOPY
Author(s):Westerfield, J. H.

Subject(s):Large amplitude motions, internal rotation
Abstract:The microwave spectrum of o-fluorotuene has been investigated at -12 $^{\circ}$C from 8.7-26.5 GHz with waveguide chirped-pulse Fourier transform microwave spectroscopy (CP-FTMW). This molecule has a measured $V_{3}$ barrier of 238.3 \wn. The low barrier height resulted in some challenges when fitting the excited states in XIAM. This work improves on our previous fit by extending into the 18-26.5 GHz frequency range and by switching to use the RAM36 fitting software instead. Based on newly collected data and our previous assignments of excited torsional states, a global fit of the ground and first two excited states has been conducted in RAM36. Additionally, scans were taken at 3 $^{\circ}$C, 19 $^{\circ}$C, and 35 $^{\circ}$C to increase the population of the excited torsional modes. Details of the fit including improvements from previous work will be discussed in the talk.
