In this paper,(2+1) resonance-enhanced multiphoton ionization(REMPI) spectra of CF radical between 260—360nm have been investigated- CF radicals were produced by a pulsed dc discharge in the mixtures of Ar/CF4,Ar/CF2Cl2 or Ar/CF3COOH-A new vibrational progression of 5p Rydberg state with band origin of 67746cm-1 were observed between 260—305nm-The vibrational frequency ω′=1848cm-1,inharmonic constant ωe χe′=18-5cm-1 and the quantum defect δ=0-625 have been determined by the assigned REMPI spectra- Furthermore,the (2+1)REMPI spectra of CF radical between 310—360nm,were also observed and assigned as 3p(v′=2—6) resonant excitation- The related spectroscopic constants have been derived-
