â¢Doppler-limited absorption spectrum of atomic F was observed around 800â¯nm.â¢Hyperfine structures of 34 lines were analyzed for F I.â¢HFS constants A of 23 levels were reported.â¢HFS constants A of 15 levels were reported for the first time.
A high resolution absorption spectrum of neutral fluorine(F I) was observed around 800â¯nm using concentration 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 2p4(3P)3s, 2p4(3P)3p and 2p4(3P)3d configurations. The hfs constants in 2p4(3P)3s and 2p4(3P)3p configurations were compared with those obtained from experiments and calculations. Fifteen constants in 2p4(3P)3d configuration were reported - to our knowledge - for the first time.
