Abstract

In the progress of wavenumber traceability using polystyrene films, different peak-seeking algorithms are discussed in this paper. Conclusion shows that in commonly used methods, spline method, center of gravity method and the second derivative method, spline method is better than the others with simple algorithm and good agreement. It is strongly recommended to use in practical for calibrating FTIR spectrometer.
