## Abstract The structural analysis of carbamates derived from 2β(Ξ±βfuryl)benzaldoximes and 2β(Ξ±βfuryl)benzyl alcohols was carried out by ^1^H and ^13^C NMR spectroscopy. The conjugative and steric effects of alkyl substituents introduced on the benzene rings were found to modify the relative orien
## Abstract Vicinal and geminal ^13^CO~2~Hο£Ώ^1^H coupling constants are reported for malic and thiomalic acids at various pH values and related, in a comparative manner, to the known conformational information obtained by ^1^H NMR.
The complex multiplet proton NMR pattern at 360 MHz of the propionic side chains in methyl pheophorbides and a pheofarnesin derived from bacteriochZorophyZl-d is capletely analyzed; the major preferred orientation in solution is found to be different from that determined by single crystal X-ray stud
