Using simple algebra, Stewart showed plasma pH is dependent on the strong ion difference (SID) of the solution, the partial pressure of CO2 (pCO2), and the total concentration of weak acids (A tot).

K c is the combined equilibrium and solubility constant for CO2 (2.45 × 10−11 mol2/(L2*mmHg)), K 3 is the second dissociation constant of carbonic acid (5.76 × 10−11 mol/L), K w is the autoionization constant of water applied to plasma (2.39 × 10−14 mol2/L2), K a is the weak acid dissociation constant (1.77 × 10−7 mol/L), and A tot is the total concentration of weak acids [23].

The purpose of this paper is to show that it is possible to increase the diameter and length of the nanostructures of a framework formed of oriented polypyrrole nanowires that has been prepared by a templateless electrochemical method based on the use of a pyrrole solution containing a high concentration of weak-acid anion and a low concentration of non-acidic anion.

Since FT-IR spectra are of the bulk material, it could be argued that there is an increase in the concentration of weaker (longer), more reactive Mo-S bonds produced with increasing decomposition pressure.
