| Abstract: | A new method for the calibration of wavelength in a measurement of high resolution molecular absorption spectra by referring the standard spectrum of iodine molecule is presented in this paper Segment offset is employed in the calibration of wavelength, while the data smoothing, baseline determining and peak fitting are applied to preprocess the spectral data A visual software is provided for automatically calibrating wavelength with a friendly style of mutual dialogue between human and computer The software has been used to calibrate the absorption spectra of N + 2 molecular ion in the visible region 16 422-17 896 cm -1 , the absolute accuracy is about 0 006 cm -1 |
