Chemi-ionization

A process by means of which gaseous molecules are ionized when they interact with other internally excited gaseous molecules or molecular moieties. See also associative ionization. Note that this term is not synonymous with chemical ionization.

Chemi-ionization

http://goldbook.iupac.org/C01044.html

This refers to a process whereby gaseous molecules are ionized when they interact with other internally excited gaseous molecules or molecular moieties. Chemi-ionization and chemical ionization are two terms which should not be used interchangeably. See also: associative ionization, chemical ionization
