Absorption spectra of sodium uranyl acetate single crystals were obtained at low temperatures. Seven lines were found, arranged in a characteristic fashion and exhibiting a high degree of circular dichroism. Absorption coefficient curves corresponding to several bands of crystalline origin observed at 20 deg K were plotted ...

Analyses of the absorption bands of uranyl acetate and nitrate were carried out utilizing the results obtained from the polarization characteristics in the absorption spectra of single crystals in different directions at liquid air temperature. (auth)
Sodium acetate is known for its ability to supercool. It freezes at 130 degrees, but can exist as a liquid at a much lower temperature. In order to melt solidified sodium acetate, however, every single crystal must liquify, otherwise the material will recrystallize. Sodium acetate has been used ...

Effects of the additions of cobalt (II) acetate hexahydrate and DL-malic acid on the growth and various properties of ammonium dihydrogen orthophosphate single crystals grown by slow evaporation method have been studied. The grown crystals were subjected to UV-vis, microhardness, dielectric, piezoelectric, high ...

We report controlled ignition of magnetization reversal avalanches by surface acoustic waves in a single crystal of acetate. Our data show that the speed of the avalanche exhibits maxima on the magnetic field at the tunneling resonances of Mn(12). Combined with the evidence of magnetic deflagration in Mn(12) ...

Local time-resolved measurements of fast reversal of the magnetization of single crystals of Mn12-acetate indicate that the magnetization avalanche spreads as a narrow interface that propagates through the crystal at a constant velocity that is roughly 2 orders of magnitude smaller than the speed of sound. We argue ...

Quantum mechanical tunneling of the magnetic moment has been observed in several single-molecule magnets, including Mn12-acetate, but the tunneling mechanism is not entirely understood. It has been proposed that tunneling occurs due to defects in the crystal structure. These defects can be studied through their effect on the ...

Following the removal of radioiodine and radioruthenium, Cs-137 is extracted as the tetraphenylborate complex into amyl acetate. The extract is then gamma counted in a well crystal. A single determination can be completed in one hour. (auth)
A supersaturated solution of sodium acetate is poured onto one small sodium acetate crystal. Crystals form from the liquid immediately upon contact with the seed crystal. A thermometer shows that the crystallization process is exothermic. A chemical hot pack is shown as an ...
The reaction of acetic acid with stoichiometric and reduced rutile TiO(2)(011) single-crystal surfaces has been studied under dark and UV illumination conditions. The surface coverage after the dissociative adsorption of acetic acid with respect to Ti was found to be 0.55. Monitoring XPS Ti, O, and C lines revealed that the surface ...

A detailed analysis of the course of the reaction of steroid sapogenins with NaNO(2) and BF(3).Et(2)O in acetic acid is presented and some evidences on the involved mechanism are provided. Two new products of the studied reaction were isolated and unambiguously characterized with the aid of NMR and single crystal X-ray diffraction. ...
An EPR study of x-ray irradiated isobutyrate and n-butyrate doped strontium acetate hemihydrate has been made. The n-butyrate radical exhibited anistropy while the isobutyrate did not. The n-butyrate radical ion has a spectrum of 8 lines of equal intensit...
