 Title: DOES WATER PREFER TO DONATE A PROTON TO AN F OR TO a Cl ATOM? - A ROTATIONAL STUDY OF CH$_{3}$CHClF...H$_{2}$O Creators: Feng, Gang; Evangelisti, Luca; Caminati, W.; Favero, Laura B.; Grabow, Jens-Uwe; Xia, Zhining Issue Date: 2011 Abstract: We measured the molecular beam Fourier transform microwave spectra of six isotopologues of the 1:1 adduct of CH$_{3}$CHClF with water. The water prefers to form an O-H...F rather than an O-H...Cl hydrogen bond. This is exactly the contrary of what observed in the chlorofluoromethane-water adduct, where a O-H...Cl link was formed . Besides the rotational constants, the quadrupole coupling constants of the chlorine atom have been determined. In addition, information on the internal dynamics has been obtained.
