摘要：

The relative position of the O-H stretching frequency of Bronsted acid sites in microporous solids is found to be correlated with the gradient norm of the electrostatic potential and, unlike previous attempts to provide a unified picture of the vibrational properties in such solids, the correlation is found for all structural and compositional variants studied to date.
