文摘

The practical computation process of 2D correlation spectra and the influence of pretreatment factors such as noise reduction, peak position shift have been discussed in this paper. The excessive noise reduction and peak position shift would lead to erroneous interpretation of 2D spectra. Two-dimensional correlation dynamic mechanical spectroscopy is suitable for the analysis of relaxation processes if with appropriate external perturbation.
