โฌI and =C NMR spectral data for 21 N-rnethyltetrahydroquinoxalines annelated with furan, p p l e , imidazole or thiazole rings are reported. Unambiguous assignments of the ring junction =C resonances were made on the basis of selective decoupling experiments and with the aid of one-bond and long-ran

and t3C-NMR spectra of compositionally homogeneous samples of chlorinated natural rubber containing 0.4-3.0 CI/C 5 have been investigated. In the samples of composition CI/C 5 ~< 1 there are no units containing > 1 chlorine atom, meaning that chlorine does not add to C-----C double bond. Simultaneou
A 'H NMR study of methyl, ethyl, n-propyl, isopropyl and allyl alcohols adsorbed on charcoals with various pore structures showed that the adsorption mechanism is by capillary condensation in pores with radii smaller than Mdi, and by mono-/multi-layer adsorption on the solid surface of pores with la
## Abstract A complete analysis of the ^1^H and ^13^C spectra of the representative series of heteroaryl vinyl ethers and sulfides and heteroaryl styryl sulfides was carried out. The electronic and spatial structures of these compounds are discussed. It was shown that the CโHยท ยท ยทN intramolecular i
A systematic study of the thermal cyclisation of isomeric di-p-anisyldiphenylcyclooctatriene derivatives, and of the facile isomerisation of the resulting dihydrosemibullvalenes, with 'H/13C nmr-structure correlations, supports earlier proposals for rearrangement mechanism. In earlier papers 1,2,3
