Natural abundance "0 NMR was studied in ClOaF, CIO,, CIOT3. ClOzr' and C102AsF6 as pure liquids or in solution. Chemiwl shifts are reported for all these compounds. In C103I'. a line shape analysis and a longitudmal relaxation mcxurement gives the indirect coupling constant J(Cl-"0) = 108 f 5 Hz and the quadrupolar interaction of "0, e*qQ/lz = 14 f 1.5 MIIZ.

## 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
