摘　　要：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.
