Table II must be used with care in anomalous cases in which the transition probability for ionization of the molecule is very low in some energy ranges (e.g., acetylene, benzene, methylamine). In such cases higher RE s, not included in the table and normally of small importance, may be responsible for the charge exchange processes although with small cross-sections (cf. 9, 13).

It is always important in thermochemical studies to be aware of the temperature at which the thermochemical properties are determined, and to combine only those properties at the same temperature. Temperature corrections can be made by using integrated heat capacities over the temperature ranges in question. However, it is often assumed that the temperature corrections for ionization energies and electron affinities are small (<1 kJ/mol) and therefore can be neglected.
