Structural characterization of octahedral metal complexes of [MX3(py)3] type with three pyridines as revealed by 2H NMR spectra
Autor: J. Ivan Legg, Sumio Kaizaki
Publikováno v: Inorganica Chimica Acta. 218:179-184
Deuterium NMR spectra of a series of mer-[MX3(py-d5)3] type complexes where M=Cr(III), Mo(III) and X=Cl−, Br−, F−, NCS− have been measured to determine the geometrical structure. Most of them provided a decisive criteria for this purpose with

Construction and evaluation of a sensitive, inexpensive pH stat/titrator system
Autor: J. Ivan Legg, Brian Warner, Gerhard Boehme, Mickey S. Urdea, Karl H. Pool
Publikováno v: Analytical Biochemistry. 106:175-185
A sensitive, inexpensively constructed pH stat-autotitrator is described. In the pH stat mode of operation a digitally controlled buret adds titrant to a reaction mixture at a rate proportional to the differences between the solution pH and the stat
