The NMR chemical shifts of alkali and thallium(I) salts with various monovalent anions have been measured in N-methylformamide solution. Lithium-7 chemical shifts are virtually concentration and counter-ion independent, presumably due to an absence of direct cation-anion interactions. The sodium-23,...

The Internal Structures of Liquid N-Methylformide - N, N-Dimethylformamide Binary Mixtures The 1H-NMR spectra of liquid binary mixtures N-methylformamide (NMF) - N, N-dimethylformamide (DMF), were recorded at 298 K within nearly the whole range o... CM Kinart,WJ Kinart,A Kolasiński - ...
The 1H-NMR spectra of liquid binary mixtures N-methylformamide (NMF) - N, N-dimethylformamide (DMF), were recorded at 298 K within nearly the whole range of mixed solvent compositions. From these data were found the values of the spectral structural parameter, (NMF - DMF). The viscosities...
