Noncovalent Interactions in the Molecular Geometries of 4-Methylthiazole···H₂O and 5-Methylthiazole···H₂O Revealed by Microwave Spectroscopy.

ABSTRACT: The pure rotational spectra of 4-methylthiazole···H₂O and 5-methylthiazole···H₂O were recorded by chirped-pulse Fourier transform microwave (CP-FTMW) spectroscopy. Each complex was generated within the rotationally cold environment of a gas sample undergoing supersonic expansion in the presence of an argon buffer gas. The spectra of five isotopologues of each complex have been measured and analyzed to determine the rotational constants, A₀, B₀, and C₀; centrifugal distortion constants, D_J, D_JK, and d₁; nuclear quadrupole coupling constants, χ_aa(N3) and [χ_bb(N3) - χ_cc(N3)]; a
