Probing pores : Adsorbed species on a zeolite are perturbed by pressure jumps (see picture; top), relaxation by means of diffusion and adsorption follows and is monitored by fast IR (middle). 2D maps are obtained by a second Fourier transform (bottom): the spectrum of each adsorbate/site pair is distinguished.
