Title:Impact Ft-mw Spectroscopy Of Organic Rings: Investigation Of The Conformational Landscape
Author(s):Wachsmuth, Dennis

Subject(s):Structure determination
Abstract:Organic rings are common building blocks in biologically active molecules. In contrast to six-membered rings, cycloalkanes with seven or more ring atoms have a less rigid structure which allows for conformational diversity and complex internal dynamics. The broadband \itshape in-phase/quadrature-phase-modulation passage-acquired-coherence technique \upshape (\mbox{IMPACT}) FT-microwave spectroscopy is the ideal experimental method to gain insight into the conformational freedom and structure of these cyclic motifs.\\ The combination of high spectral resolution ($<10$~kHz) and frequency accuracy with a 1~GHz wideband acquisition range per experimental pulse (over the entire $2$ to $26.5$~GHz range) makes the \mbox{IMPACT} spectrometer a time-saving tool when it comes to the investigation of fine or hyperfine effects and/or wide tunelling splittings. In this communication we will present the rotational spectra of several organic seven-membered rings, reporting on their conformational preferences and molecular structures.
