β¦ Synopsis
Solid state NMR spectra and the corresponding liquid state spectra have been interrelated through two-dimensional experiments with a fast temperature jump during the mixing time. This jump must, as a minimum requirement, be shorter than the relevant spin lattice relaxation times, and was implemented using a COz laser heater. As the first demonstration of this experiment we report a 2D 'H solid-liquid spectrum of camphor. Suggested applications of future 2D temperature jump expe~ments include studies of reversible chemical reactions, reorientational dynamics, phase behavior, and magnetic and electrical properties.

Heterogeneous catalysis is still the industrial cornerstone in the production of basic chemicals, polymers, and in some instances fine chemicals. One of the key problems in developing new heterogeneous catalysts has been the low content of active sites coupled with their diversity, which makes their
