## Abstract ^1^H, ^13^C and ^15^N NMR chemical shifts of 10 substituted pyrazolo[1,5‐__a__]pyrimidines were assigned based on DQF ^1^H, ^1^H COSY, PFG ^1^H, ^13^C HMQC and PFG ^1^H,X (X = ^13^C and ^15^N) HMBC experiments and on literature data. Copyright © 2002 John Wiley & Sons, Ltd.

✦ Synopsis
A considerable degree of variability exists in the way that LH, ~3C and ~SN chemical shifts are reported and referenced for biomolecules. In this article we explore some of the reasons for this situation and propose guidelines for future chemical shift referencing and for conversion from many common IH, 13C and 15N chemical shift standards, now used in biomolecular NMR, to those proposed here.

Triple-resonance experiments capable of correlating directly bonded and proximate carbon and nitrogen backbone sites of uniformly 13 C-and 15 N-labeled peptides in stationary oriented samples are described. The pulse sequences integrate cross-polarization from 1 H to 13 C and from 13 C to 15 N with
## Abstract The dipeptide alanylproline has been prepared with the proline residue both ^13^C (15%) and ^15^N (95%) enriched. ^15^N NMR spectra of alanylproline reveal signals for both possible conformations—__cis__ and __trans__—of the dipeptide backbone in solution. Different p__K__ values for bo
## Abstract The ^1^H and ^13^C NMR resonances of 16 purine glucosides were assigned by a combination of one‐ and two‐dimensional NMR experiments, including gs‐COSY, gs‐HSQC, and gs‐HMBC, in order to characterize the effect of substituent and the position of glucose unit on the NMR chemical shifts.
