For the zeolite offretite, a formula is proposed which includes the framework Si/AI ratio (R), the partitioning ratio of AI over two crystallographically non-equivalent tetrahedral sites (r) and intensities of the observed peaks in the 29Si MAS NMR spectrum. By this formula, the framework Si/AI rati
