dc.description.abstractThe rotational spectra of the parent species of two conformers of the amino acid derivative leucinamide have been recorded between 10.5 and 20 GHz using a Balle-Flygare Fourier-transform microwave spectrometer. 6 \emph{a}- and \emph{b}-type rotational transitions were recorded for conformer I and 23 \emph{a}- and \emph{b}-type rotational transitions were recorded for conformer II. The rotational constants are $A=2274.94(9)$ MHz, $B=1033.336(7)$ MHz, and $C=911.732(3)$ MHz and $A=2752.775(8)$ MHz, $B=843.502(1)$ MHz, and $C=796.721(1)$ MHz for conformers I and II respectively. The congested hyperfine patterns arising from the two $^{14}$N nuclei were not resolved. Comparison of the experimental moments of inertia to those derived from the lowest energy ab initio (MP2/6-311++G(d,p)) structures indicates gas-phase backbone structures that differ from both the crystal structures of leucinamide, \emph{602-603}, 2002, 71-78.} and the gas-phase structures of the amino acid leucine, \emph{8}, 2007, 599-604.}.en_US
