The 13 C NMR spectra of twelve isomeric 2‐and 4‐(E)‐stilbenyloxyalkylthiouracils have been calculated and fully assigned. The A i and A i K empirical parameters of 4‐ketopyrimidyl‐2‐thioalkoxy, 2‐ketopyrimidyl‐4‐thioalkoxy, 2‐( E ) ‐stilbenyloxyalkyl, 2‐( E )‐stilbenyloxyalkylthio, 4‐( E )‐stilbenyloxyalkyl and 4‐( E )‐stilbenyloxyalkylthio groups were calculated for the predictions of the chemical shifts of substituted uracils and benzenes.
