PA"a scale

Goedheer et al. [148, 149] have attempted to formulate scaling laws. They varied the power P, pressure p, and frequency co and measured the dc self-bias Vdc. From their experimental results (frequency range 60-100 MHz, pressure range 20-60 Pa) a scaling law was formulated [148] ... 

The pA"a scale of HB donors (free acids) on the right and the p a scale of acceptors (protonated bases BH" ) on the left are placed in such a way that the most common acids and bases are matched in order to achieve strengthened hydrogen bonds.
