Especially since the advent of digital computing have scientists in various spectroscopy fields been interested in numerical methods and procedural algorithms for locating all sorts of peaks in their data. I am most familiar with gaussian peak searches. These usually involve cross-correlation filtering; the seminal paper in this field seems to be Mariscotti's. But there are a number of other algorithms in use, including various simplex, linear least squares, non-linear and derivative methods. A pretty good compilation of many of the commonly used algorithms can be found at: http://www.galactic.com/galactic/science/algo.htm Hope this helps. -- (Timo) - .. -- ---
