Dissociation energies of PH and PH+

Journal of Quantitative Spectroscopy and Radiative Transfer, 1995
Abstract Dissociation energies for the ground electronic states of diatomic PH and PH+ are determined by fitting empirical potential functions to the respective RKRV curves using correlation coefficients. The estimated ground state dissociation energies of PH and PH+ are 3.10 and 3.20 eV respectively by the curve fitting procedure using Lippincott ...

Intracellular pH

Physiological Reviews, 1981
Albert Roos and Walter F. Boron, “Intracellular pH,” vol. 61, no. 2, April 1981, p. 308: The constant R in Equations 14 and 16 should be M, M being defined as PHA/PA. The constant R' in Equations 15 and 17 should be N, N being defined as PB/PHB. The constant R in the definitions of α, β, ɣ, and δ is the gas constant.

pH IN ACTION

Acta Horticulturae, 2001
Based on fundamental chemical relations, well-established in chemical engineering and chemical technology over almost a century, the effects of pH in food and agricultural products will be deduced for different situations and processes. Based on simple equilibria and dissociation of water, salts, acids and bases, and considering the reaction of ...

pH

2023
pH is undoubtedly the most important chemical soil characteristic that determines the chemical environment of higher plants and soil microbes. There are few reactions involving any component of the soil or of its biological inhabitants that are not sensitive to soil pH. This sensitivity must be recognized in any soil-management system.

APPROXIMATION OF PH/PH/c RETRIAL QUEUE WITH PH-RETRIAL TIME

Asia-Pacific Journal of Operational Research, 2014
We consider the PH/PH/c retrial queues with PH-retrial time. Approximation formulae for the distribution of the number of customers in service facility, sojourn time distribution and the mean number of customers in orbit are presented. We provide an approximation for GI/G/c retrial queue with general retrial time by approximating the general ...

[Mo{P(Ph)2OC6H3(Ph)(η6-Ph)}(CO)2] [PDF]

open access: possibleActa Crystallographica Section C Crystal Structure Communications, 1994
Dicarbonyl[(2-η 6 -phenyl-6-phenylphenoxy)diphenylphosphine-P]molybdenum contains a new phosphine ligand bound to Mo through the O atom and via an η 6 -arene interaction. A «three-legged-piano-stool» geometry is present with Mo-P=2.354 (1) A, Mo-C(carbonyl)=1.942 (4) and 1.944 (5) A and Mo-C(aryl)=2.295 (4)-2.339 (4 ...

Constant pH simulations of pH responsive polymers

The Journal of Chemical Physics, 2016
Polyacidic polymers can change structure over a narrow range of pH in a competition between the hydrophobic effect, which favors a compact state, and electrostatic repulsion, which favors an extended state. Constant pH molecular dynamics computer simulations of poly(methacrylic acid) reveal that there are two types of structural changes, one local and ...

ON THE VISCOSITY AND pH OF SYNOVIAL FLUID AND THE pH OF BLOOD

The Journal of Bone and Joint Surgery. British volume, 1959
1. The results of viscosity measurements on a number of normal, traumatic and osteoarthritic synovial fluids from human knee joints are described and discussed. 2. A decrease of the viscosity of normal synovial fluid with age has been found. 3. The decrease of the viscosity with age and in the pathological groups is analysed and its relation to the ...

Mitochondria and pH

Nature, 1967
THE concept of intracellular pH depends on the assumption that the cell is either not divided into compartments, or that the volumes of the compartments are large enough to contain a statistically meaningful number of hydrogen ions, the “intracellular pH” in this case being a mean of the pH values in the various compartments.
