Some of the thermochemical data derived from this study include Ddegree}(Msup minus}}-S) > 103 kcal/mol and Ddegree}(Msup minus}}-SH) = 83 plus minus}9 kcal/mol. Finally, a brief survey of the reactivity of Vsup minus}}, Crsup minus}}, and Mosup minus}} with selected organosulfur compounds is also reported. 79 refs., 3 figs., 7 tabs

transform ion cyclotron resonance (FTICR) spectroscopic methods have been applied to examine the gas phase reactions of the metal carbonyl anions [metal(CO) 4 ] − , metalCr, Mn; [metal(CO) 3 ] − , metalCr, Mn, Fe; and [metal(CO) 2 ] − , metalFe, Ni with 13 C-labelled carbonylsulfide. Measurements of temporal variations of ionic product distributions have allowed mechanisms to be proposed to account for
explored for the preparation of metal oxides. Adaptation of nonhydrolytic sol-gel chemistry to non-oxide systems offers an elegant route to transition-metalsulfides. The method can be exploited for the facile and reproducible synthesis of iron sulfide crystallizing in the troilite structure. This phase is only found in meteorites and planets and has previously been obtained by high-temperature or high-energy
Abstract This paper reports the results attained by experimental research for determination of the mechanism of the pyrite oxidation process under non-isothermal conditions. Kinetic parameters of the process were determined according to the relationships of Kissinger and Ozawa.

orbitals is attributed to vibronic effects. The metal 2p32 spectra show the effects of multiplet splitting and satellites due to shake-up or shake-off processes. The valence band spectra consist of slightly overlapping contributions of anion p and metal 3d electrons. The metal 3d spectrum of FeS2 has a single strong peak of width 0.9 eV. The 3d spectra of the other compounds show structure due to several
