  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.

  The dissociative recombination coefficients, α, have been measured at 300 K for several polyatomic positive ion species using a flowing afterglow/Langmuir probe (FALP) apparatus. The α range from 1.1 × 10−7 cm3 s−1 for H2F+ to 2.2 × 10−6 cm3 s−1 for the clustered species H+(CH3OH)3. Several of the ionic species included in this study are considered to be involved in the synthesis of interstellar molecules

  使用流动的余辉/ Langmuir探针（FALP）装置，对几种多原子正离子物种在300 K下测量了离解重组系数α。对于H 2 F +，α的范围为1.1×10 -7 cm 3 s -1；对于簇状物种H +（CH 3 OH）3，α的范围为2.2×10 -6 cm 3 s -1。这项研究中包括的几种离子物质被认为与星际分子的合成有关。
