Nuclear Magnetic Resonance in Heterogeneous Catalysis,the angular moment is expressed in . = ./2. units. The natural abundance, the relative sensitivity (compared to that of the proton), and the quadrupolar moment (where appropriate) of a limited selection of nuclei often encountered in catalysis are listed in Table 5.2.

The situation in this area has improved greatly during the last 20 years, but is still not entirely satisfactory. The second objective concerns the catalytic process. Schematically heterogeneous catalytic reactions involve five steps:

https://doi.org/10.1007/978-3-031-07297-0nd adsorption, this spectroscopy is complementary to classical IR transmission because the selection rules are different, but in some cases it is the only spectroscopy able to detect adsorbent vibrations in a wave number range where the support itself is not transparent to IR radiation.

Epilogue: A Department of Object Studies?,n electron microscopes (STEM) equipped with X-ray analyzers can be used to determine the local composition of catalysts with a spatial resolution as good as 1 nm in the case of field emission gun STEM. This is why electron microscopy is now in widespread use for catalyst characterization.
