## Abstract The ^1^H NMR spectra of thirteen dihydro‐1,2‐oxazine derivatives are reported. Spin decoupling allows analysis of the spectra, features of which include homoallylic couplings of +2 to +2·5 Hz, allylic couplings of −1·5 to −1·7 Hz and vicinal couplings across __sp__^2^ to __sp__^3^ carbo
