A high resolution absorption spectrum of neutral fluorine(F I) was observed around 800 nm using con- centration modulation absorption spectroscopy with a tunable Ti : Sapphire laser. The fluorine atoms were produced by discharging the mixed gases of helium and sulfur hexafluoride (SF6) in a glass tube. Thirty four hyperfine structure ( hfs ) resolved transitions were analyzed to obtain 23 magnetic dipole hfs constants A for 2 p 4 ( 3 P)3 s , 2 p 4 ( 3 P)3 p and 2 p 4 ( 3 P)3 d configurations. The hfs constants in 2 p 4 ( 3 P)3 s and 2 p 4 ( 3 P)3 p configurations were compared with those obtained from experiments and calculations. Fifteen constants in 2 p 4 ( 3 P)3 d configuration were reported - to our knowledge - for the first time.
