8 INDEX OF SYMBOLS
This index lists symbols for physical quantities, units, some selected mathematical operators, states of aggregation, processes, and particles. Qualifying subscripts and superscripts, etc., are generally omitted from this index, so that for example $E_{\rm{p}}$ for potential energy, and $E_{\rm{ea}}$ for electron affinity are both indexed under $E$ for energy. The Latin alphabet is indexed ahead of the Greek alphabet, lower case letters ahead of upper case, bold ahead of italic, ahead of roman, and single letter symbols ahead of multiletter ones. When more than one page reference is given, bold print is used to indicate the general (defining) reference. Numerical entries for the corresponding quantities are underlined. The acronym ‘ifc’ for a page number refers to the inside front cover.
