    [3] [3] . The pure rotational spectra of 9-fluorenone have been gradually captured in the millimeterwave and microwave range[10-11]. The present work aims to expand the scope of laboratory observation of 9-fluorenone in the microwave C-band (4~8 GHz), further supporting the astrophysical research of this molecule and other PAHs. Specifically, the pure rotational measurement (mostly between 4.5 and 6.6 GHz)of 9-fluorenone in the vibrational ground state is reported to promote more extensive exploration of PAHs in the fields of astrophysics. In addition, a global fitting analysis is carried out by combining with the existing rotational data in the microwave region, conducive to the accurate characterization of the ground state structure of this molecule.
