Openspectralworks - "a suit of Programs for viewing, editing, and manipulating spectral data"
OpenSpectralworks is a suite of programs for viewing and manipulating digitized spectroscopic data, i.e. data consisting of an optical measurement such as light absorbance as a function of wavelength or energy of the light (or other radiation) involved. It is most useful for those spectroscopies for which the Lambert-Beer law or an analogous relation holds.

Two problems are of special interest to the initiating author:
1. Linear LS fitting of experimental spectra to linear combinations of known basis spectra to determine the composition of a mixture (and its changes with time).
2. Global fitting of multi-wavelength, multi-spectral data ("3D data") to thermodynamic or kinetic models to determine the parameters involved and the spectra of the different model components.. Examples are potentiometric or pH titrations data, and multiexponential fitting.
