Correlating phosphorus core binding energies, phosphorus lone pair ionization potentials, and proton affinities of tervalent phosphorus compounds

Abstract

Phosphorus core binding energies have been determined for a wide variety of tervalent phosphorus compounds. These values are compared with literature values of the corresponding lone pair ionization potentials and proton affinities. No single correlation is found between all the core binding energies and the corresponding lone pair ionization potentials or proton affinities, but the lone pair ionization potentials are linearly correlated with the proton affinities. It is concluded that the electronic relaxations accompanying lone-pair ionization and proton attachment are similar in character and energy, whereas the electronic relaxation accompanying core ionization is of a somewhat different type, in which atomic orbital rehybridization plays a relatively unimportant role.

Effect of surface phosphorus functionalities of activated carbons containing oxygen and nitrogen on electrochemical capacitance

“…Taking into account the presence of phosphorus in all carbons under the study, O-I and O-II entities also cover the contributions from non-bridging oxygen bonded to phosphorus P=O and bridging oxygen, C–O–P, of phosphates [27,28]. …”

The role of second-neighbor effects in photoemission: Are silicon surfaces and interfaces special?

“…The measured splitting between the two C 1s peaks is 8.5Ϯ0.1 eV as compared to a value of 8.6Ϯ0.1 eV reported for the gas phase. 16,22 Given experimental uncertainties, this is essentially exact agreement.…”

Using photoelectron spectroscopy for the investigation of substituent effects in N‐ and P‐centered radical cations

“…Using 15 narrow series (Tables 1–5, series I–XV) taken from the literature,1–4, 6–13, 16, 18, 20–23 it is possible to consider the effects of substituents X on the core‐electron binding energies E and ionization potentials I measured by photoelectron spectroscopy as well as on the energies E obtained from quantum chemical calculations. It follows from Tables 1–5 that values of E and I are substituent dependent.…”

“…X‐ray (XPS) and ultraviolet (UPS) photoelectron spectroscopy is widely applied to the measurement of the core‐electron binding energies ( E ) and vertical ionization potentials ( I ) for gaseous nitrogenated1–13 as well as organophosphorus1, 2, 6, 14–23 compounds. Photoelectron spectroscopy is based on the use of a gas‐phase ionization process initiated by photons with the energy h ν: where R C BX n is a neutral molecule, RBX n is a radical cation, and e − is an electron 2, 3.…”
