The CH3O2(+) product ion of the thermal energy reaction between O2(+) and CH4 has been studied in reaction with a number of neutral molecules.The reactivity pattern demonstrates very convincingly that the structure of the ion is methylene hydroperoxy cation, CH2OOH(+), in contrast to previous reports that the ion is protonated formic acid, HC(OH)2(+) or HC(O)OH2(+).From these and other data the heat of formation of this ion is determined to be between 182 and 188 kcal/mol.

The rate coefficients for a variety of reactions involving OH+, H2O+, and H3O+ with CS2, H2S, SO2, NO, NO2, N2O, N2, O2, CH4, CO2, CO, NH3, and H2 are obtained with a selected ion flow tube.The product channels include proton transfer, charge transfer, atom abstraction, and association.Most of the reaction rates are fast and have high reaction efficiencies.Reaction of OH+ with NO2 is found to produce both NO2+ and NO+; even though both reaction channels are also exothermic with H2O+, only NO2+ is produced.H3O+ is found to undergo association reactions with SO2 and N2O and H2O+ does so with CO2 and N2O.The reaction of H2O+ with N2O also involves a second-order process in addition to the association pathway.

, p. 431 - 436 (2001)
B0.54C0.28N0.18 precursor powder with turbostratic structure was prepared by using melamine and boric acid. The precursor was transformed into orthorhombic B2CN under definite high pressure and temperature conditions. The composition of the orthorhombic B2CN powder is B0.47C0.23N0.30. Its lattice parameters are a=0.4776 nm, b=0.4585 nm and c=0.3629 nm. A strong absorption band from 1088 to 1385cm-1 of orthorhombic B2CN was observed by infrared measurement. In the photoluminescence (PL) spectrum of orthorhombic B2CN powder measured at room temperature, a broad peak corresponding to its band-edge emission centers at 374 nm.

Interaction between the ion dipole and the ion-induced dipole in reactions of the polar ion ArH+3
Praxmarer, C.,Hansel, A.,Lindinger, W.
, p. 8884 - 8889 (1994)
The reactions of the highly polar ion ArH+3 with the nonpolar neutrals Xe, Kr, CH4, CO, NO, O2, and N2 and with the polar neutrals SO2, H2O, NH3, CH3I, and C2H5I have been investigated in a selected ion flow drift tube experiment at near thermal conditions.The rate coefficients obtained have typically 15percent-35percent larger values than the collisional limiting values kL and kADO obtained by the Langevin and ADO (average dipole orientation) theory, respectively.These data are explained on the basis of the interaction between the dipole of ArH+3 and the ion-induced dipole and the permenent dipole, respectively, of the neutral reactants.Rate coefficients for the reactions of H+3 with the above neutrals were also obtained for comparison, as well as the zero field mobility of ArH+3 in helium being (18.5+/-1.5) cm2/V s.The ion KrD+3 (KrH+3) was detected unambiguously for the first time.Its dissociation energy is larger than 0.29 eV which is the lower limit of the dissociation energy of ArH+3.

The complex formation reactions of boric and boronic acids (RB(OH)2: R=OH, n-Bu, Ph, and m-NO2Ph) with 4-isopropyltropolone (Hipt) and chromotropic acid (H2cht2-) have been studied kinetically at various pH. The reactions of H2ipt+ with boronic acids were faster than those of Hipt by a factor of 1.5-11, and fully deprotonated ipt- also reacted with m-NO2PhB(OH)2, but slower than Hipt. The tetrahedral m-NO2PhB(OH)3- ion did not react with Hipt. Reaction routes for the complexation of boric acid with chromotropic acid could not be specified because of the unexpected problem of proton ambiguity. Mechanism for the reactions of boronic acids with bidentate ligands was discussed in terms of rate determining chelate ring closure. It was concluded that at least one proton is necessary for the OH- in the tetrahedral intermediates to be eliminated smoothly as water, and a doubly hydrogen-bonded intermediate was proposed for the reactions with diprotic ligands.

, p. 837 - 846 (2008/10/08)
The interaction of water with GeCl4, SnCl4, and AsCl3 was studied by IR spectroscopy. The results demonstrate that these chlorides contain molecular water in monomeric form. At water concentrations above 10-2 mol/l, GeCl4 also contains H3O+ ions. The mechanisms of GeCl4 and AsCl3 hydrolysis were studied over a wide range of water concentrations.
