## Abstract The ^13^C NMR spectra of eight 2,5โdiarylโ1,4โdithiins were recorded and signals were assigned. A linear correlation was observed between the electronegativity of the substituent groups on Cโ10,10โฒ and the chemical shifts of Cโ10,10โฒ after applying corrections for the magnetic anisotrop
## Abstract Carbonโ13 NMR chemical shifts (CDCl~3~ and C~6~D~6~ solvents) and relaxation times (__T__~1~) were determined for carbons in a series of allenic esters [RR~1~C๏ฃพC๏ฃพCHCO~2~ Et; (1) R = R~1~ = H; (2) R = H, R~1~ = CH~3~; (3) R = H, R~1~ = CH~3~CH~2~; (4) R = R~1~ = CH~3~; (5) R = CH~3~, R~1
## Abstract The ^13^C NMR spectra of a series of 2,3โdiarylโ1,3โthiazolidinโ4โones were measured and the resonance signals produced by the methylene, methine and carbonyl groups of the heterocyclic ring assigned. The variations in their chemical shifts were examined and the influence of __S__โoxida
