## Abstract The ^1^H n.m.r. spectra of doubly ^15^N labelled urea and 1,3‐dimethylurea have been analysed with the aid of computer simulation. ^1^H^1^H, ^1^H^15^N, ^15^N^15^N and ^13^C^15^N (from ^13^C Ft spectra) couplings are reported.
A study of 15N-15N and 15N-13C spin couplings in some 15N labeled mesoionic 1-oxa and 1-thia-2,3,4-triazoles

## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^‐alkyl‐__N__^2^‐arylthioureas. The absence of decoalescence of the __N__^1^‐alkyl group carbon signals down to 190 K, the europium‐induced chemical shifts and the molecular mechanics calculations indicate that the preferred c
## Abstract The ^15^N chemical shifts and ^1^H^15^N and ^13^C^15^N coupling constants of nine monolabelled indazoles were measured and assigned. The experimental values are discussed in terms of the indazolic and iso‐indazolic structures, and compared with literature data for other related hetero
## Abstract We report here the syntheses of tetrazole‐^13^C and 1,2,4‐triazole‐1,2‐^15^N~2~ by simple, one‐step procedures using common, commercially available, isotopically‐labeled starting materials. tetrazole‐ ^13^C is conveniently prepared from K^13^CN and NaN~3~ in 70% yield, almost twice the
## Abstract ^13^C and ^15^N NMR spectra of eight substituted 1,2,4‐triazines were measured and assigned. The assignments of the ^13^C NMR spectra were based on the substituent chemical shifts and ^__n__^__J__(C,H) coupling constants. ^15^N NMR chemical shifts generally showing well separated ranges
## Abstract One‐ and two‐dimensional NMR spectra of Tröger's base, (±)‐2,8‐dimethyl‐6__H__,12__H__‐5,11‐methanodibenzo[__b,f__][1,5]diazocine labelled on one of the nitrogen atoms, have been used to determine the chemical shifts, coupling constants, and Δ^13^C(^15^N) isotope shifts. Copyright © 200
