文摘

In this work a two-dimensional correlation spectroscopy method is extended using a continuous two-dimensional spectral surface approximation. The paper presents the results of calculating of the correlation spectra for ozonolysis ethylene reaction at constant temperature. A new method for peaks searching in the 1D spectrum was developed to improve the quality of calculations. In contrast to the Noda’s theory [1] on asynchronous spectrum, the one peak corresponding to secondary ozonide indicating on the certain sequence of events in the reaction is found. The advantage of our technique is the continuity of the function approximating the spectrum. Keywords correlation spectroscopy wavelet analysis sequence of events peak search IR spectra ozonolysis
