Autor: V. I. Vasil'chenko, I. I. Shman'ko, I. F. Tsymbal, E. V. Ryl'tsev
Publikováno v: Theoretical and Experimental Chemistry. 27:214-217
The H-bonds of aldehydes (acetaldehyde and its mono-, di-, and trichloro derivatives) acting as proton donors in solutions and in carbon tetrachloride were studied by IR absorption spectroscopy. Triethylphosphine oxide, one of the strongest acceptors
