## Abstract The ^17^O NMR chemical shift data for a series of substituted 10‐methyleneanthrones and related 10‐alkylanthrones in acetonitrile solution at 75°C are reported. The ^17^O NMR chemical shift value of 10‐methyleneanthrone is shielded by __ca__. 35 ppm compared with that of anthraquinone.
## Abstract Natural abundance ^17^O NMR spectroscopic data, in toluene‐__d__~8~ at 90°C, were obtained for different classes of steroids, including androstanes, estranes, pregnanes, cholanes and cholestanes. Only routine acquisition parameters were used in combination with linear prediction methods
