The 13 C NMR spectra of a wide variety of organic substrates bound to 2% cross‐linked polystyrenes may be obtained routinely, provided the resins can be sufficiently swollen. The 13 C chemical shifts of polymer‐bound trityl alcohol, polymer‐bound monotrityl ethers of the symmertrical diols HO (CH 2 ) n OH ( n =2, 4, 6, 7, 9 and 10), and some related intermediates in the solid phase synthesis of insect pheromones are presented. 13 C shift additivity correlations, differing little from those in free trityl ethers, are drawn.
