Abstract
The microwave spectrum of 2-methylfuran has been measured at temperatures between 0~$^irc}$C and 50~$^irc}$C from 8.7--18.3~GHz with waveguide chirped-pulse Fourier transform microwave spectroscopy (CP-FTMW). Using the enhanced sensitivity of this technique relative to that of prior measurements from Stark-modulated instruments, we have been able to extend the assignments of the lowest energy A- and E-states from Norris and Krisher \textbf{51}, 403 (1969).} to include transitions up to J = 60 and K$_\textrm{a}$ = 35. We will also report on our progress towards assigning higher-lying states and compare the fit results to those from \textit{ab initio} calculations.
