  A selected ion flow tube study of the reactions of the PH⁺_n ions (n=0 to 4) with several molecular gases at 300 K

  摘要：

  The reactions of ions in the series PH+n (n=0 to 4) have been studied at 300 K with CH3NH2, PH3, NH3, CH3CCH, H2S, C2H4, CH3OH, COS, C2H2, O2, H2O, CH4, HCN, CO2, CO, and H2 using a selected ion flow tube (SIFT) apparatus. The majority are fast binary reactions, the measured rate coefficients, k, being close to the respective collisional values, and for reactions involving polyatomic reactant molecules multiple product ions are observed. Most reaction mechanisms are represented in this large number of reactions including charge transfer, proton transfer, atom abstraction and especially evident is phosphorus atom insertion in which product ions such as HnPN+, HnPO+, HnPS+ and HnCmP+ are formed. The reactions of the PH+n ions (n=0 to 2) with CO2, CO, and H2 proceed by the process of ternary association except for the P+ reaction with CO2, in which PO+ is formed in a fast binary reaction. PH+4 reacts only with CH3NH2 and NH3 by fast proton transfer, a process which is always rapid when it is exothermic. Upper limits to the heats of formation of HPO+, H2PO+, PC2H2+ and HCP have also been deduced from their observation as products of some of the reactions.

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

  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.
