Abstract：Wavelet analysis and wavelet denoising was applied to analyse the data of two dimensional correlation IR spectroscopy of traditional Chinese medicine for the first time in this article. The results showed that, after denoising, the authors can decrease the interference to the synchronous spectra of two dimensional correlation IR spectroscopy effectively, and tone up the signal peaks and separate the peaks which overlap together before denoising. In this way, the authors can not only improve the spectral revolution, but also get more spectral informations.
