## Abstract ^13^C and ^15^N NMR chemical shifts were measured for __N__^1^โalkylโ__N__^2^โarylthioureas. The absence of decoalescence of the __N__^1^โalkyl group carbon signals down to 190 K, the europiumโinduced chemical shifts and the molecular mechanics calculations indicate that the preferred c

## REFERENCE DATA carbons, for various substituent groups and positions were carried out by gated decoupling with NOE. ## RESULTS AND DISCUSSION The I3C NMR chemical shifts of the compounds are shown in Tables 123; 'J(CH) and long-range coupling constants of 2, 9, 13 and 18, measured by gated d
The M y proton-coupled 15N NMR spectra of pyrimidine with natural isotope abundance and of bis-labelled [1,3-"N2]p~dine, obtained using single pulse experiments, are described. The "N and 'H spectra are analysed for "J, 'J and 4J(NH) as well as N,N and H,H coupling constants.
