ON T H E HUSTINGS—Three Rice students prepare a mailing fo r the Professors fo r Johnson-Humphrey-Yarborough (see p. 6). Elsewhere, a national group, "Scientists and Engineers fo r Johnson-Humphrey" will fo rm a local chapter this Monday a t 8 pm a t the Houston Theatre Center. Rice president K. S. Pitzer, TSU President Nabr i t and hear t surgeon Michael DeBakey were among the founders of the ...

Major uncertainties exist with respect to the aqueous geochemical evolution of the Martian surface. Considering the prevailing cryogenic climates and the abundance of salts and iron minerals on Mars, any attempt at comprehensive modeling of Martian aqueous chemistry should include iron chemistry and be valid at low temperatures and high solution concentrations. The objectives of this paper were...

In this work, the results concerning to the mean activity coefficient measurements for NaCl in the (glycerol + water) system using the potentiometric method are reported. The potentiometric measurements were performed on the galvanic cells without liquid junction of the type: Ag|AgCl|NaCl (m), glycerol (wt%), H2O (1 - wt)%|Na-ISE, in various mixed solvent systems containing 0, 5, 10,...

A procedure that automatically identifies internal rotation modes and rotating groups during the normal mode vibrational analysis is outlined, and an improved approximation to the corrections for the thermodynamic functions is proposed. The identification and the characterization of the internal rotation modes require no user intervention and make extensive use of the information imbedded in th...

New evidence bearing upon the anomalous properties of xenon hexafluoride has been obtained via the ab initio molecular orbital approach applied successfully to the diand tetrafluorides in paper 1. Structures of both XeFt and XeF6 are governed by a stereochemically active lone pair. In the case of the square-pyramidal cation the F .. -Xe-Feq angle calculated for the bare ion is within 2° of the ...
