In order to investigate a substitution effect and a heat treatment effect, we have prepared polycrystalline samples of CePt 3Γd Si 1ΓΎd Γ°d ΒΌ Γ0:05 $ 0:15Γ: We have carried out the DC and AC magnetic susceptibility on this system. It is found that the magnetic susceptibility at low temperatures is enh
## Abstract The ^13^C NMR spectra of 40 vicinally substituted 2β and 3βnitropyridines were recorded. The observed chemical shifts are, in general, nonβadditive. These results are discussed in terms of the effects of 2β, 3β and 4βsubstitutents on the ring carbons and of the position of the fixed nit
