Corrigendum: Difluorocarbene studied with Threshold Photoelectron Spectroscopy (TPES): Measurement of the first Adiabatic Ionization Energy (AIE) of CF2 (Chem. Eur. J, (2008), 14, (11452–11460), 10.1002/chem.200801699)

The authors would like to report a correction to this work. In this study of the reactive intermediate difluorocarbene (CF₂) with threshold photoelectron spectroscopy (TPES), the first adiabatic ionization energy (AIE) of CF₂ was determined as (11.362±0.005) eV. However, this value did not take into account the lowering of the AIE, which arises from field ionization of high-n Rydberg states, by the extraction field (F) used. This Stark effect correction (δ) is 6.1 √F,^[1] where δ is in cm⁻¹ and F is in V cm⁻¹. The value of F used was 100.0 V cm⁻¹, which gives δ as 7.6 meV. Hence, the AIE should be increased by 7.6 meV to give a corrected AIE value of (11.370±0.005) eV.
