“…21 (ii) The formation of 1:2 complexes (broad band between 3100 and 2000 cm -1 ) is observed after outgassing the excess of alcohol at room temperature or at 323 K ( Figure 3C-f, C-g). (iii) Evacuation at higher temperature eliminates most of the alcohol species.…”

This paper reports a new way of modulating the strength of the Brønsted acid sites of a porous solid. Our approach consists of the grafting of various polar molecules (H 2 O, CD 3 OH, CF 3 CH 2 OH, and (CF 3 ) 2 CHOH) on MIL-100(Cr), a mesoporous crystallized chromium carboxylate with accessible unsaturated metal sites. We demonstrate, using infrared spectroscopy, that all these compounds do coordinate on the coordinatively unsaturated Cr 3+ sites. This generates controlled Brønsted acid sites whose strength, measured by CO adsorption at 100 K, depends on the nature of the adsorbate. It can vary from H 0 ) -3 (CD 3 OH) to -8 ((CF 3 ) 2 CHOH).

“…It is worth noting that HFIP alone shows broad strong OH stretching band in the liquid phase (3430 cm À1 ) or in the solid phase (3260 cm À1 ) [11] while, in the cluster 1, this band appears at lower frequency ($3000 cm À1 ).…”

This paper reports microwave spectroscopic and theoretical investigations on the interaction of water with hexafluoroisopropanol (HFIP). The HFIP monomer can exist in two conformations, antiperiplanar (AP) and synclinical (SC). The former is about 5 kJ mol(-1) more stable than the latter. Theoretical calculations predicted three potential minima for the complex, two having AP and one having SC conformations. Though, the binding energy for the HFIP(SC)···H2O turned out to be larger than that for the other two conformers having HFIP in the AP form, the global minimum for the complex in the potential energy hypersurface had HFIP in the AP form. Experimental rotational constants for four isotopologues measured using a pulsed nozzle Fourier transform microwave spectrometer, correspond to the global minimum in the potential energy hypersurface. The structural parameters and the internal dynamics of the complex could be determined from the rotational spectra of the four isotopologues. The global minimum has the HFIP(AP) as a hydrogen bond donor forming a strong hydrogen bond with H2O. To characterize the strength of the bonding and to probe the other interactions within the complex, atoms in molecules, non-covalent interaction index and natural bond orbital theoretical analyses have been performed.
