Abstract
The problem of finding individual line parameters from experimental absorption spectra is reduced to the minimization of a function of N variables. The spectra may consist of overlapping, closely spaced, and broadened lines, and need not be of high resolution. It is assumed, however, that the general response function of the instrument is given and that the line shapes are known functions of wave number and of the parameter in question for each of the N lines involved. An example of the use of the method is given by outlining a successful computer program for determining half-widths in infrared spectra, and showing results of numerical tests.Keywords
