Abstract
We report the observation and assignment of the rotational spectra of dibenzofuran measured in the range of 2 - 6 GHz with a newly constructed broadband chirped-pulse Fourier transform microwave (cp-FTMW) spectrometer. An analysis of the microwave spectra led to the assignment of 40 b -type transitions, resulting in the accurate determination of the rotational constants A = 2278.19770(38) MHz, B = 601.12248(10) MHz, and C = 475.753120(98) MHz.
