摘      要：PbF,a valuable candidate for measuring the electron electric dipole moment(eEDM),is of great significance in measuring its spectrum and deriving its molecular constants in *** the present work,the rovibronic spectrum of the B^(2)Σ^(+)-X_(1)^(2)Π_(1/2) transition of PbF in a wavelength range of 260 nm-285 nm is studied by the laser ablation/laser induced fluorescence *** molecular parameters of the X_(1)^(2)Π_(1/2)(v=0)and B^(2)Σ+(v =0,1)states are derived from the recorded spectra of the(0,0)and(1,0)bands of the B^(2)Σ+-X_(1)^(2)Π_(1/2) ***,the Franck-Condon factors(FCFs)of the transitions between the B^(2)Σ+and X_(1)^(2)Π_(1/2)states are calculated by the RKR/LEVEL method and the Morse potential method,respectively.
