## Abstract The ^17^O NMR chemical shifts of five enriched amino acids have been measured under strictly controlled conditions of concentration, ionic strength, pH and temperature. The Ξ±, Ξ² and Ξ±, Ξ³ carboxyl resonances of aspartic and glutamic acid, respectively, have been resolved. Line widths wer
## 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. Routine memory overflow was avoided by using a combination of solvent suppression
## Abstract The ^17^O and ^13^C chemical shifts (Ξ΄) of 14 Ξ±,Ξ²βunsaturated aldehydes and ketones and 33 acyl derivatives RXC = O (X = Cl, OH, OMe, OEt, NH~2~ and R = H or alkyl) have been measured. In the unsaturated carbonyl series, a correlation exists between Ξ΄ ^17^O and the Ο electron density at
## 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 2βposition. Estimates of the dihedral angle
