The Infrared Spectra of Three Aluminum Alkoxides

Abstract

NOTESVol. 60 solute value of the standard is not known closer than * 10%. Therefore, the actinium fluoride neutron emission rate determined experimentally is probably no better than f 15 to 20%.However, since the neutron emission from the fluoride sample, and the theoretical growth curve agreed quite closely over the growth period, and since the theoretical and experimental maximum values are of the same order of .magnitude, one can conclude that the values that were used for computation are approximately correct, and the neutron yields obtained by extrapolation from data in reference six are not unreasonable. Thus, the use of neutron counting techniques for quantitative detection of trace quantities of fluorine in actinium appears feasible. There seems to be no serious objection to extending the technique to the detection of fluorine or other light elements, such as beryllium or boron, in any of the alpha-active heavy elements.We wish t o acknowledge the assistance of Mr.R. D. Joyner and Mr. S. R. Orr, who found time between their regular duties to prepare the actinium fluoride and to perform the calorimetric assay. We are also grateful tq Dr. H. W. Schamp for his assistance with the sealing problem.

Infrared spectra of hydrogen sulfide, carbon disulfide, sulfur dioxide, methanethiol, and ethanethiol absorbed on iron and nickel

“…It is a well-known principle that where there is a large separation in force constant or vibration frequencies, the modes of motion are fairly independent (Wilson, Decius, et al, 1955). A case similar to this one is the agreement between alkoxide spectra and free alcohol spectra that has been found for the infrared spectra of Al and Ti alkoxides (Bell, Heisler, et al, 1953;Guertin, Wiberley, et al, 1956;Kriegsmann and Licht, 1958;Wilhoit, Burton, et al, 1962).…”

“…Theoretically, the Al-O-Al linkages give rise to absorptions between 945 and 990 cm À1 , while those of Al-O-C linkages are between 1028 and 1070 cm À1 . 39 At the same time, C-O-C bonds also have absorptions between 900 and 1150 cm À1 , which can be introduced by the additive PEO. Fig.…”
