Understanding the behavior of Hofmeister anions of ionic liquids (ILs) on protein stability
helps to shed light on how the anions interact with proteins in aqueous solution and is a long …

Since its original inception, a great deal has been learned about the nature, properties, and
applications of the H-bond. This review summarizes some of the unexpected paths that …

We provide a simple explanation for X− H bond contraction and the associated blue shift
and decrease of intensity in IR spectrum of the so-called improper hydrogen bonds. This …

The X− H bond length in X− H.. Y hydrogen bonded complexes is controlled by a balance of
two main factors acting in opposite directions.“XH bond lengthening” due to n (Y)→ σ*(H− X) …

A novel technology of removing organic sulfur from coal was proposed by microwave
irradiation combined with NaOH-H 2 O 2. The organic sulfur removal degree and the …

The first local minimum of the formic acid dimer exhibits simultaneously red-shifted O–H⋯ O
and blue-shifted C–H⋯ O hydrogen bonds. The improper, blue-shifted hydrogen bond was …

For blue-shifted hydrogen-bonded systems, the hydrogen stretching frequency increases
rather than decreases on complexation. In computations at various levels of theory, the blue …

In this paper we put forward the idea that the various “improper, blue-shifting” hydrogen
bond systems discussed in the literature are all of essentially the same nature and occur …

Herein we demonstrate that an external electric field (EEF) acts as an accessory
catalyst/inhibitor for Diels–Alder (DA) reactions. When the EEF is oriented along the …

Abstract σ-Hole bonding is a noncovalent interaction between a region of positive
electrostatic potential on the outer surface of a Group V, VI, or VII covalently-bonded atom (a …
