Abstract
This work presents a structural approach for determination of proton affinities of molecules. In proton-bound dimer [X…H…M]+, M and X compete with each other to capture the proton. The correlation between proton affinities of a series of molecules, M, and X…H bond length was studied while X was a common molecule in the all proton-bound dimers. Linear relationships were observed between proton affinities of a series of alcohols, ethers, aldehydes, ketones and amines and X…H bond length, where H2O and HF were used as X. The method was employed for the measurement of proton affinities of (HF)1–10 clusters using NH3 and H2O as common molecules, [NH3…H…(HF)n]+ and [H2O…H…(HF)n]+. A linear correlation was observed for the PAs of (HF)n clusters versus N…H bond length.
