## Abstract ^17^O chemical shifts of four amino acids at natural abundance have been obtained. Sensitivity was enhanced by accumulating a large number of scans or employing high concentrations at elevated temperature.

## Abstract ^1^H NMR spectra are reported for Michler's ketone and twenty of its derivatives, along with ^13^C chemical shifts for five of the compounds. ^1^H chemical shifts show only small changes with increasing substitution at the sterically hindered 2‐position. Estimates of the dihedral angle
