Abstract

"\vspace{0.1in} \begin{wrapfigure}{r}{0pt} \includegraphics[width=5.25cm]{dimer.eps} \end{wrapfigure} We report the rotational and distortion constants of 3 conformers of 2-fluorobenzoic acid, 2 conformers of 3-fluorobenzoic acid and a single conformer of 4-fluorobenzoic acid fitted from the assignment of pure rotational transitions measured in the microwave region from 4-12 GHz. We also recorded the microwave spectrum and assigned the b-dipole transitions of a very large dimer of 3-fluorobenzoic acid which has very small rotational constants. The b-dipole transitions were split and assigned to the two states 0+ and 0- vibrational states with rotational constants: A$^{+}$= 1157.01939( 75) MHz, B$^{+}$ = 95.45061(199) MHz and C$^{+}$ = 88.21514(124) and A$^{-}$= 1157.02249( 46), B$^{-}$ = 95.45110( 74) and C$^{-}$88.24425( 70). This large dimer is a milestone in our groups efforts at ""climbing"" the ladder to very large dimers that contain dynamics information."
