摘要

本文采用EХSY方法，考虑交叉弛豫的贡献，测量了水分子和deuteroporphyrin IX二甲酯环内NH基团参与下的质子交换常数。通过与DOSY方法的比较，可以更完整地描绘出去卟啉二甲酯的交换过程，指出主要的限制阶段，并确定相应的速率常数。

Proton Exchange of Intracyclic NH Groups of Deuteroporphyrin IX Dimethyl Ester and Water Molecules according to the Data of Exchange Spectroscopy (EXSY)

In this work, the EХSY method was used to measure the proton exchange rate constant with the participation of water molecules and intracyclic NH groups of dimethyl ester of deuteroporphyrin IX, taking into account the contribution of cross-relaxation. Comparison with the similar measurements by the DOSY method makes it possible to construct a more complete picture of exchange processes for dimethyl ester of deuteroporphyrin IX, to point out the main limiting stages, and determine the corresponding rate constants.
