Because of their use as catalysts, the volume of papers published on the nature of the acid sites in zeolites is impressive. The number of acid sites is correctly estimated and their chemical nature is known. There are however numerous domains still largely unexplored, such as the structural descrip
## Abstract ^13^C chemical shifts are reported for a series of 2‐substituted 1,3‐dimethylbenzenes: comparisons of these values with those for the corresponding monosubstituted benzenes reveal, in some cases, large differences in the __para__‐carbon substituent chemical shifts, which are attributabl
