Comment on: Negative ions, molecular electron affinity and orbital structure of cata‐condensed polycyclic aromatic hydrocarbons by Rustem V. Khatymov, Mars V. Muftakhov and Pavel V. Shchukin

“…The ionization energy of hexacene in the NIST database 6.36 (2) eV and that of naphtho[1,2‐b]triphenylene 7.40 (2) eV give AE a = EN‐IE of 8.00 − 6.36 = 1.64 eV and 8.00 − 7.40 = 0.60 eV, in agreement with the reported AE a values of 1.58 (5) eV and 0.61 (3) eV from half‐wave reduction potentials . Finally, it is suggested that, assuming that thermal decomposition does not take place, the ground state AE a of hexacene and pentacene could be measured from high‐temperature mass spectrometric thermal data as applied to SF 6 and C 7 F 14 …”

“…In 2004, the electron affinities in the NIST database were reviewed . Since 2004, several negative ion mass spectrometric studies have been carried out on AHC or other compounds so it is pertinent to revisit the ECD data . This communication provides ground state AE a from ECD or other data for the 15 compounds listed in Table , to be used for comparison with mass spectrometric data.…”
