## Abstract By the use of the ^1^Hο£Ώ^1^H and ^1^Hο£Ώ^31^P coupling constants in two analogues of aspartic acid i.e. 3βaminoβ3βphosphonatopropionic and 3βaminoβ3β(methylphosphinato) propionic acids, it was shown that the six parameter formulation for the evaluation of mole fractions of three staggered
A series of five-, six-, and seven-membered 1,3-dinitroso-, l-nitroso-3-nitro-, and 1,3-dinitro-1,3-diazacycloalkanes were investigated by 'H, I3C, and "N NMR spectroscopy. Hindered rotation of the nitrosamine group leads to the existence of rotational isomers. The relative populations of rotamer fo
