Ions likely irrelevant to LJP calculations

These ions are very unlikely to affect the calculated LJP due to exceptionally low mobility, no charge, or common use at extremely low concentrations (see the theory page for details).

By listing such molecules here we confirm we know they exist, and remind users they are probably not important for caculating LJP.
