1 DUAL BEAM SPECTRUM CALIBRATION ANALYZER FIELD OF THE INVENTION [0001] The present invention relates to the field of spectral calibration analysis, particularly involving dual beam spectrum calibration analyzer. GENERALBACKGROUND [0002]Spectral analysis is mainly used for correcting the emission spectrum analysis of the transitions between energy levels and absorption spectra of molecules, including the pure rotational spectrum of the vibration rotation spectrum band and electronic spectral bands. Pure rotational spectra of molecules are produced by molecular rotational transitions between energy levels, having a distribution in the far infrared band; the main observation is usually about absorption spectroscopy. Vibration - rotation spectra is produced by transitions between the different vibrational levels and the rotational levels, which have some dense lines, distributed in the near-infrared band. [0003]An electronic spectrum is produced by transitions with different levels of vibration and different rotation between different electronic states, which can be divided into a number of bands; the emission spectrums have a distribution in the visible or ultraviolet wavelength and can be observed. [0004]However, due to the absence of dipole moment in the non-polar molecules, rotational spectrum and vibration - rotation spectrum band do not exist, only polar molecules have such a spectral band. Therefore, the existing analytical device also has limitations for non-polar molecule spectroscopy; so it is necessary to make reasonable technical solutions for these problems to be addressed.
