Collisional dissociation and chemical relaxation of alkali halide molecules: 2000-4200 K
Milstein, Richard,Berry, R. Stephen
, p. 6025 - 6037 (1984)
Shock-induced dissociation and the subsequent chemical relaxation processes of diatomic alkali halide molecules have been studied by time-resolved absorption spectrometry of alkali atoms, halide ions, and alkali halide molecules.The salts studied in detai
The production kinetics for rare gas alkali ions
Schumann, M.,Langhoff, H.
, p. 5440 - 5443 (1989)
In a recent paper it was shown that rare gas ions form bound molecular states which decay by emission of radiation in the VUV.They are potential candidates as storage media for VUV lasers.In the present investigation the ions Kr+K, Kr+Cs, Xe+K, and Xe+Cs are produced by electron beam excitation of suitable gas mixtures with He as buffer gas.Studies of the reaction kinetics were performed for Kr+K.The rate constant for the reaction Kr+ + K + He was determined to be 2.8 X 10-30 cm3s-1.Kr+K is strongly quenched by plasma electrons and by reaction with Kr.The fluorescence yield at intense excitation was determined to be about 5 X 10-2 VUV quanta per He+ ion.

The homo- and heteropolychalcogenide anions, Chn2- (n = 1, 2, 3, 4; Ch = Se and/or Te) and the hydrochalcogenide anions, HCh-, have been prepared and characterized in solution by 1H, 77Se, 123/s
Studies on trifluoromethanesulfonic acid. Part 2. Conductivities of solutions of metal trifluoromethanesulfonates and other bases in trifluoromethanesulfonic acid

Electrical conductivity measurements are reported for solutions in trifluoromethanesulfonic acid of a number of simple and complex bases, including univalent and divalent metal trifluoromethanesulfonates.The univalent metal salts, water, aniline, and acetic acid behave as fully dissociated bases, while the alkaline earth metal salts show considerable ion association.The trifluoromethanesulfonate anion appears to have an abnormally high mobility, as compared to the metal cations, and is believed to conduct by a proton-transfer mechanism.Dissociation constants for some weak organic bases and association constants for strontium and barium trifluoromethanesulfonates are estimated.Sulfuric acid behaves as a weak electrolyte, while sulfur trioxide is effectively a non-electrolyte.The conductivities of potassium nitrate and potassium dihydrogenphosphate are consistent with the formation of the nitryl cation and the phocphate acidium ion, respectively.
