We have found that "C nmr spectroscopy is a powerful tool for the determination of the structures of &, trans isomers in the phosphorinane family. It is more definitive than 'H nmr spectroscopy; the carbon signals are well separated and have several unique features pointing to the structure, whereas

## Abstract The configurational assignment of stereoisomeric 3βbromoβ3βacyl derivatives of steroids in both the 5Ξ± and 5Ξ² series has been carried out by comparing the ^13^C chemical shifts of Cβ3. A downfield shift is observed for Cβ3, bearing a bromine and an acyl group, on going from the isomer w
Analysis of the 'H NMR spectra of several monothiocsrbonohydraones, some of them synthesized for the first time, shows that they exist as two structural isomers. Whereas, in general, the derivatives of aromatic aldehydes conform to a linear structure, the aliphatic carbonyl derivatives conform to he
## Synopsis '"C-nmr spectroscopy was used to determine the location of the structured segment of the chain of histone H1 in water and NaCl solutions. The segment found (41-89) is contained in the area proposed by others on the basis of 'H-nmr studies. The number of basic groups left in the mobile
