Determination of the first ionization energy of furan (C4H4O) from an extrapolation of two nd Rydberg series observed in the mass-resolved (2+1) resonance enhanced multiphoton ionization spectrum
The first ionization energy of furan (C4H4O) has been determined from a short extrapolation of two nd (n = 6-22) Rydberg series observed in the mass-resolved (2 + 1) resonance enhanced multiphoton ionization spectrum as IE = 71673 +/- 3 cm(-1). This value confirms the higher of the two values in the literature. (C) 2004 Elsevier B.V. All rights reserved.
