eng	Study of acidity of chabazite zeolite	One of the most direct methods, which does not affect the OH group itself, for example by interaction with another molecule, is based on monitoring the frequency of vibration as a function of temperature. Acidity is associated with the interaction strength and thus the frequency of vibration of the O-H group. Studied samples of chabazites were deconvolved into individual vibration contributions and types of OH center and the dependence of their vibration in temperature was plotted. In this work we have shown different temperature behaviour of each Brønsted site in temperature and also the isotopic factor, which remains constant in whole temperature range for all experiments, was calculated.
