Identification of two conformationally trapped n-propanol-water dimers in a supersonic expansion
Abstract
Two conformers of the n-propanol-water dimer have been observed in a supersonic expansion using chirped-pulse Fourier-transform microwave (CPFTMW) spectroscopy. Structural assignments reveal the n-propanol sub-unit is conformationally trapped, with its methyl group in both Gauche and Trans orientations. Despite different carbon backbone conformations, both dimers display the same water-donor/alcohol-acceptor hydrogen bonding motif. This work builds upon other reported alcohol-water dimers and upon previous work detailing the trapping of small molecules into multiple structural minima in rare gas supersonic expansions.
