Structured emission spectra have been observed from ND3 excited at 2139 Å and 2144 Å. The emission is short-lived (τ < 10?10 s) and has been assigned to the ND3() → ND3() fluorescence transition. 相似文献

Solution properties of water-soluble synthetic polymer, 3,3-ionene and 6,6-ionene chloride and bromide disolved in water-acetone mixtures up to acetone content 50 wt% were investigated. Their partial molar volumes V

with respect to the cation of backbone polymer chain and the counter-anion was confirmed quantitatively. The ionic additivity of V

in their relation to the counterion binding of ionene polymers. Effects of ionic sites on the ionene are strong but they don't break the solvation layer. 相似文献

Cefixime (CX), an oral cephalosporin antibiotic, and its metabolites in human digestive organs were separated by various modes of high-performance capillary electrophoresis. The zone electrophoresis mode in phosphate buffer (pH 6.8) containing 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulphonate gave the best separation, permitting the complete resolution of CX and all of five metabolites. On the other hand, the plain zone electrophoresis mode in phosphate buffer (pH 6.8) offered a simple procedure for the direct determination of urinary CX concentration using intact urine samples. 相似文献

Treatment of [Cp*Ru(dppe)]+ with B-triethynyl-N-trimethylborazine and piperidine produces the trimetallic complex [Cp*Ru(dppe)(CC)]3B3N3Me3, the structure of which has been confirmed by X-ray diffraction. Reaction of RuHCl(CO)(PPh3)3 with B-triethynyl-N-trimethylborazine produces the trimetallic complex [RuCl(CO)(PPh3)2(CH=CH)]3B3N3Me3. 相似文献

The laser-induced oxidation of ethane by O2 at 318 K was investigated with varying the pressure between 12–91 atm. The reaction condition was regarded as the supercritical phase above 50–60 atm, depending on the O2 fraction. Ethanol, acetaldehyde, and CO2 were mainly produced at any reaction conditions, together with small amounts of C1 compounds and formic esters. The kinetic discussion for the time dependence indicated that the consecutive photolysis of primary products takes place during the subsequent laser irradiation period. The branching ratio to CO2 formation in the primary process in the supercritical phase is much smaller than that in the gas phase, and the selectivities for ethanol and acetaldehyde show a discontinuous change near the critical point. These facts show that the supercritical phase affects this complex radical reaction system. The primary photoabsorption process is also discussed. 相似文献
