Abstract

A significant challenge in room temperature microwave spectroscopy is the large number of transitions in a spectrum at 298 K. At these temperatures, multiple vibrational states are populated, each of which has its own distinct spectrum. Assignment of these spectra can be accomplished through a combination of experimental and computational techniques. Room temperature microwave spectra of fluorobenzene, iodobenzene, and anisole were collected and analyzed. For fluorobenzene the fit parameters for previously assigned states were refined. For iodobenzene, in addition to assigning new lines to transitions, the hyperfine terms for three excited states were resolved. Finally for anisole the fit parameters for previously assigned states were refined and two new preliminary fits were obtained. As a proof of principle, broadband 2-D measurements and narrowband double resonance measurements were made on iodobenzene. The implication of these measurement techniques for future spectral assignment are discussed.
