✦ Synopsis
Abstract
Substituted 2‐(phenylamino)‐5‐phenyl‐1,3,4‐oxadiazoles were studied by ^15^N NMR spectroscopy. All signals were assigned on the basis of HMQC and HMBC experiments. Chemical shifts values were correlated with empirical Hammett parameters as well as with calculated electron densities and chemical shieldings. Copyright © 2006 John Wiley & Sons, Ltd.

## Abstract Three series of substituted 1,3,4‐oxadiazoles were studied by ^17^O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values. Copyright © 2011 John Wiley & Sons, Ltd.
N NMR chemical shifts were measured for a series of substituted 5-amino-1,2,4-triazoles. The assignment of isomeric structures agrees with earlier results obtained with the use of proton-coupled I3C NMR.
