Spectroscopic study of telluric acid and selenic acid in hydrogen fluoride and the hydrolysis of tellurium hexafluoride

“…This species must be monofluorotelluric acid. It is probably identical with one of the species obtained by the controlled hydrolysis of tellurium hexafluoride; namely, the one appearing at the lowest field of all species observed (5cci3f " 22.5 ppm). The skeletal vibrations of (HOjsTeF should by analogy with HOTeFs give a relatively simple vibrational spectrum as substitutions of a fluorine atom for an -OH group should be barely discernible.…”

Acid-base Equilibria in Non-aqueous Solvents with Particular Reference to Glacial Acetic Acid.

“…Hammett (29) has given a highly interesting discussion of the role of the properties of the solvent in determining acidity, and has clearly distinguished between the inferences that may legitimately be made from colorimetric work with indicators of various types and from electrometric measurements. Numerous papers of Hantzsch (31, 31a, 31b, 33) should also be cited in this connection, as well as the recent work of Schwarzenbach (48), Fredenhagen (12,13,14) and Rabinowitsch (46). Bjerrum's (3, 4) studies of ion-partition coefficients present a novel method of attack on the problem of relative acidities in different solvents.…”

The Hydrogen Bond and Coördination.

“…By far the most interesting of the associated solvents is hydrogen fluoride, and it is here that the strongest hydrogen bond is formed. The remarkable work of Fredenhagen (2) probably needs to be confirmed in some particulars by other investigators, but it furnishes us with conclusions. It will be more logical, however, to consider this substance in connection with anion solvation and to continue the discussion of its behavior under that topic in the latter part of this paper.…”
