Sequence length of ethylene oxide and the amount of end groups in polyacetal copolymers were determined using proton NMR. Peaks from ethylene oxide usually appear in the region from 3.5 to 3.8 ppm, when tetramethylsilane was used as the internal standard. These peaks were divided into three triad se

The 'H chemical shifts of the active bridge protons and their temperature dependences were measured in various solvents for a number of ortho-Mannich bases containing proton-donor (OH) and proton-acceptor (N) centres of varying strength. It was found that a maximum on the plot of 6 , versus ApK, occ
## Abstract The ^1^H NMR spectra of the protonated and unprotonated forms of __cis__‐ and __trans‐N‐methylhexahydroisoindoline__, of 1,3,3,4,4‐pentamethylpyrrolidine and of 1,3,3‐trimethylpyrrolidine were analyzed. The coupling constants between the NH⊕ and the CH protons α to the nitrogen allowed
## Abstract Deuteration of 2‐phenylthiazolidine, and its complexation with the shift reagent tris(1,1,1,2,2,3,3‐heptafluoro‐7,7‐dimethyl‐4,6‐octanedionato)europium, have been used to study the signals and conformation of the heterocyclic protons and to interpret the ^1^H NMR spectrum of this 2‐subs
