Book Fourier Transform Microwave Spectroscopy of Gas Phase Acids and Acid base Complexes

Download or read book Fourier Transform Microwave Spectroscopy of Gas Phase Acids and Acid base Complexes written by Galen Sedo and published by . This book was released on 2008 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourier transform microwave spectroscopy, supported with ab inito and Density Functional Theory calculations, has been used to investigate gas phase acids and acid-base complexes in an effort to further our understanding of the electronic and molecular interactions occurring in these small reactive systems. The Stark effect has been measured on the 111 ← 0 00 rotational transition of the sulfuric acid monomer. The resulting dipole moment, 2.9643(67) D, represents an increase of 0.24 D over the previously reported value and is supported by high-level theoretical calculations. An examination of the CH3COOH-H2O spectrum shows an 18.6% lowering of the three-fold methyl group internal rotation barrier with the addition of a single solvent water to the acid. An argument has been made that suggests the lowering of the barrier in the acetic acid monohydrate is consistent with the structural changes in the acetic acid moiety, and the degree of proton transfer, determined from ab initio calculations, is similar to those calculated for other protic acid hydrates. The rotational spectra for the HNO3-(H2O)3 and HNO 3-N(CH3)3 complexes have also been observed. The experimental values of the 14N quadrupole coupling constants have been used to determine the degree of proton transfer away from the acid, and comparisons have been made to those determined from their optimized ab initio structures. The results show the systems to be hydrogen-bound neutral pairs with a slightly higher degree of proton transfer than similar HNO3 complexes. The microwave spectrum of the (CH3) 3CCN-SO3 complex has been observed and analysis of the data reveals a Lewis acid-base complex with intermolecular bonding nearly halfway between the van der Waal's and chemically bound limits. The properties of the complex are in good agreement with those predicted on the basis of the previously reported series of complexes formed between SO3 and a nitrogen-containing base.
