H and '3C chemical shifts, obtained by two-dimensional homonuclear and heteronuclear shift correlation, are reported for 8,8-diethyl-N,N-dimethyl-2-aza-8-germaspiro [4,5]decane-2 -propanamine dihydrochloride (spirogermanium). The chemical shift variations as a function of pH and the coupling constan

The iniluence of substituents on the 'H, "C and 15N NMR chemical shifts of 2-substituted 5(6)nitrobenzimidazoles and their analogues labelled with 15N in the nitro group was investigated. It was found that the substituent effects are transmitted to the carbon and hydrogen nuclei in positions 4-7 mai
## Abstract The formation of hydrogen bonds and molecular dynamics for the molecules __cis__‐1‐(2‐hydroxy‐5‐methylphenyl)ethanone oxime (**I**) and __N__‐(2‐hydroxy‐4‐methylphenyl)acetamide (**II**) have been investigated in solution using NMR. The results confirm the formation of OH···O, OH···N
