A photoelectron spectroscopic study of di-t-butylphosphazene
Abstract
Gaseous trans-ButPNBut, generated by mild gas-phase thermolysis of its more stable [2 + 1] cyclodimer, has been characterized by field-ionization mass spectrometry and U.V. photoelectron spectroscopy. The photoelectron spectrum has been assigned based on SCC-Xα model calculations for representative H EEH and E2 molecules (E2= N2, PN, or P2) and by comparison with the known ionization potentials of RNNR and E2 species. The low-energy sequence for parent dialkyldiphosphenes is deduced.
