Summary. The dissociation constants of the two oxime groups of 1,1′-bis(pyridinium-4-aldoxime)trimethylene dibromide (TMB-4) were determined using spectrophotometric data. Two numerical methods were applied to treat the overlapping equilibria. The results obtained by both agreed with each other and...
The dissociation constants of eight phenols and homoconjugation constants of the corresponding phenol–phenolate systems in propylene carbonate were determined from e.m.f. measurements. The results are compared with those obtained previously in acetonitrile and acetone. The effect of the nitro-group on...
The dissociation constants of the conjugate acids of a number of substituted benzyl phenyl ketones have been measured. Unlike the acetophenone and benzaldehyde series, there is no resonance exaltation of the effective σ-values, and inductive substituent constants (σ0) are applicable. Similar measure...
Using an oxidative addition reaction accompanied by the dissociation of two CO ligands, thiolated triosmium carbonyl with thiol linkage groups was prepared (Os3-SH) (Supplementary Figs. 8, 9)20,34. However, removing the two CO lowers the symmetry from D3h to Cs34. According to the character ...
2The second acidic dissociation constants of protonated piperazine-N,N′-bis-2-hydroxypropane-sulfonic acid (POPSO sesquisodium salt) have been determined at 12 different temperatures from (278.15 to 328.15) K including 310.15 K. Electromotive-force measurement technique was used employing hydrogen-silv...
13 C NMR study of the dissociation of tartaric and citric acids The dissociation of tartaric and citric acid was studied by the 13 C NMR method. All four dissociation constants of tartrate and citrate were determined directly from the pH-dependent shift of signals of carbon atoms making the co...

Alkaline (hyperalkaline) medium The acid dissociation constants of the alcoholic OH of gluconate and those of some structurally related ligands have been determined and were found to correlate with the stability of the calcium complex formed with the alcoholate functionality. Deprotonation of the OH ...
Accordingly, we added 25 nM of either [3H]S-CIT or [3H]IMI to membranes of COS-7 cells transiently expressing hSERT wild type (WT), and then measured the dissociation rates of the two ligands in the presence of increasing concentrations of S- or R-CIT (0.4 µM–1 mM) ...
