Abstract

We here present the first microwave study of acetohydroxamic acid (CH$_{3}$CONHOH), a glycine isomer, using a broadband chirped pulse FTMW spectrometer equipped with a laser ablation vaporization system (LA-CP-FTMW)\footnote{L. Kolesniková, I. León, E. R. Alonso, S. Mata, J. L. Alonso, J. Phys. Chem. Lett., 10 (2019), 1325-1330.}. We have characterized two distinct structures (Z-amide and E-amide) of acetohydroxamic acid in the supersonic expansion. Accurate experimental values of the $^{14}$N nuclear quadrupole coupling constants together with the rotational constants and also the barrier to the internal rotation (V$_{3}$) of the methyl group have been provided for both conformers. The precise spectroscopic information provided here could be relevant to guide readioastronomical searches of acetohydroxamic acid in the ISM.\footnote{M.
