Abstract：Accurate curve fitting of infrared spectrum data is important for building standard spectrum, and is the basic requirement for qualitative and quantitative spectral analysis. In the present paper, B-Spline was used to accurately fit the infrared spectrum data. Based on the max norm distances of B-Spline curve fitting arithmetic, this method not only resolved the curve fitting problem of infrared data, but also provided a convenient way to orient peak values of spectrum. The authors introduced the B-Spline, realized curve fitting of quadratic non-uniform B-Spline curves (for short: NUBSC), and described the precision control of curve fitting of infrared spectrum data.
