Bonding and ionization energies of N-F and P-F compounds
- 1. Argonne National Lab., IL
Description
NF3, N2F4, NF2, PF3, P2F4, PF2 and PF2I have been studied by photoionization mass spectrometry. Modified or confirmatory values have been obtained for the heats of formation of NF3+, NF2+ and NF+ and the ionization potentials of NF3 and NF2. The step-wise bond energies are deduced to be D00(NF) = 3.27 +/- 0.02 eV; D00(FN-F) 2.85 +/- 002 eV; and D00(F2N - F) = 2.47 +/- 0.01 eV. Heats of formation at 0 K have been measured for PF2+ (89.6 +/- 0.5 kcal/mole), PF+ (less than or equal to 214.8 kcal/mole) and PF2I (-142.3 +/- 1.0 kcal/mole). The directly measured ionization potential of PF2 is 8.85 +/- 0.01 eV. The step-wise bond energies are found to be D00 (PF) = 4.60 +/- 0.43 eV; D00 (FP-F) = 5.22 +/- 0.43 eV; and D00 (F2P - F) = 5.71 +/- 0.02 eV
