The experimental ECD and NIMS procedures for studying reactions of thermal electrons with molecules and negative ions are described. Gas phase electron affinities and rate constants for thermal electron attachment, electron detachment, anion dissociation and bond dissociation energies are obtained from ECD and NIMS data. Techniques to test the validity of the specific equipment and to identify problems are included. Examples of the data reduction procedure and a method to include other estimates of quantities and their uncertainties in a non-linear least squares analysis will be given. The non-linear least squares procedure for a simple two parameter two variable case is presented in the appendix.
