Abstract:

The two-photon resonance-enhanced multiphoton ionization spectrum between 285 and 288.5 nm of the 5pπE2Πr(v’=1)←X2Πr(v’’=0) band of CF radical is reported. The band is rotationally analyzed, and the spectroscopic constants of the state are first derived: σ0 = 69566.38±0.52 cm-1, A'v= 46.4±0.3 cm-1, B'v= 2.565±0.017 cm-1, D' v = (8.6±1.2)×10-6cm-1.

Key words: CF radical, REMPI, pπE2Пr state, Spectroscopic constants
