Structure, solution, electron affinity, resonance and inductive effects are the major reasons for the change. The salts tested pkas all fall between the pkas for benzoic acid and pyridine. The ionic atmosphere of the salt can change the order of acidity expected from hydrohalic studies. This change is due to steric strain produced by the 2,4-dinitrobenzyl group. Computer and graphical methods can be used to determine the equivalence point and pkas of salts.
Deviations depend upon experimental, instrumental, chemical and physical properties.
I worked with drafting, communication, orbital and work schedule programs. I also did moderate research into programming and computer-printer communication. My other duties involved documentation of reports concerning signal to noise, computer controlled sensors for heat and pressure, and radar systems. The research involved the use of optical and synthetic instrumentation. Through my use of the mainframe 3380 IBM computer and many smaller personal computers, I became quite familiar with Basic, assembly language, and the CMS operating system.
