✦ Synopsis

The 15N chemical shifts and 15N,'H coupling constants of wyosine (Y-nucleoside) triacetate were obtained through both fully proton-coupled and selectively decoupled 15N N M R spectra at natural isotopic abun-dance, using modified INEPT pulse sequences. The spectra were analysed for 2J, and 4J(NH) values. The results were compared with those for the parent compounds.

Natural abundance 13C and 15N NMR studies were carried out on a series of N -methylated and N -tert -butylated tetrazoles. Longrange 13C,1H and 15N,1H NMR coupling constants together with 1J (15N,13C) allowed unequivocal assignments of 13C and 15N chemical shifts for isomeric 1,5-and 2,5-disubstitut

## Abstract We describe direct methods for the measurement of the transverse and longitudinal ^15^N chemical shift anisotropy–dipolar cross‐correlation rates based on comparison of the ^15^N doublet components observed in ^1^H‐coupled ^1^H–^15^N HSQC‐type spectra. This allows the determination of t
