  Chemiluminescent reactions of second‐row atomic ions. II. P⁺(¹D)+H₂, D₂→PH⁺(A ²Δ), PD⁺(A ²Δ)+H,D

  摘要：

  Chemiluminescent collisions of P+ ions in a beam with H2 and D2 molecules have been observed in the energy range of 2.3 to 12.2 eVCM. A spectral analysis at the peak of the cross section, 6.4 eVCM, by means of computer-generated spectra showed the PH+ and PD+ A 2Δ–X 2Π systems, which included some previously unobserved bands. The well-known A-state predissociation was confirmed, but appears to be incomplete above its onset at N=13 for PH+(A, v=0) and N=17 for PD+(A, v=0). The formation of PH+(A) has an activation barrier of 1–1.5 eV above the thermochemical threshold, which is analogous to the Al++H2 case and may be typical of second-row ion reactions.
