Determination of the protonation constant of chloramine-B

Talanta, 1985
The protonation constant of chloramine-B has been determined at pH < 3.3 by an ionexchange method. The value found is 61 +/- 5.

Spectrophotometric determination of the first protonation constant of orthovanadate

Talanta, 1990
The first protonation constant for VO(3-)(4) has been determined spectrophotometrically at 25 degrees in 1M sodium chloride and found to have the value log K = 13.29 +/- 0.01. Individual absorption spectra for VO(3-)(4) and HVO(2-)(4) have been calculated (for the range 218-350 nm) from experimental absorbance measurements.

P.E.HSQMBC: Simultaneous measurement of proton–proton and proton–carbon coupling constants

Journal of Magnetic Resonance, 2012
A long-range optimized P.E.HSQC experiment, named P.E.HSQMBC, is proposed for the simultaneous measurement of a complete set of homonuclear and heteronuclear coupling constants from a single 2D cross-peak. The sign and the magnitude of proton-proton coupling constants are measured along the direct dimension from the relative E.COSY-type multiplet ...

Reliability of protonation constants of SNAZOXS oligomers

Talanta, 1994
Concentration protonation constants of variously protonated of oligomers of sulphoazoxine SNAZOXS were determined by regression analysis of potentiometric titration curves. The group and common parameters were estimated using different computational strategies of three regression programs, MINIQUAD, MIQUV and PSEQUAD.

Determination of protonation constants by coulometric titration

Talanta, 1987
Application of coulometric titration to the determination of the protonation constants of acids and bases offers several advantages because of its simplicity, precision and accuracy. This procedure is rapid and requires only one calibration solution of strong acid in the same solvent and at the same ionic strength as the solution of acid (or base ...
