Abstract

The gas phase microwave spectra for a dimer between water and an organometallic complex were measured using a pulsed-beam Fourier transform microwave spectrometer. 32 rotational transitions for the weakly bound complex of butadiene iron tricarbonyl and water were measured in the region of 6–14 GHz and fit to determine rotational constants of A = 973.9279(9) MHz, B = 606.1943 (4) MHz, C = 605.2675 (4) MHz. Structure A, calculated using B3LYP/aug-cc-pVTZ Empirical Dispersion = GD3, provides v = 0 rotational constants in excellent agreement with measured values. There appear to be 3 hydrogen bonds stabilizing the dimer.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
