We seek to determine the effect of competing intermolecular hydrogen bonds from water on the preferred conformation of 4-aminobutanol (4AB) monomers stabilized by intramolecular hydrogen bonds. Toward this end, the rotational spectrum of the 4-aminob

Rotational spectra of the most abundant and four 13 C isotopomers of 4-aminobutanol have been recorded in natural abundance using a Fourier-transform microwave spectrometer. For the most abundant isotopomer, 56 hyperfine components from the fifteen a

Rotational spectra of the most abundant, three 13C, and the 15N isotopologues of 3-aminopropanol have been recorded in natural abundance using a Fourier-transform microwave spectrometer. For the most abundant isotopologue, 54 hyperfine components fro

We present here the first experimental study of the microwave spectrum of deuterated 5-methyltropolone, a molecule which exhibits two large-amplitude motions: an intramolecular hydrogen transfer (deuterium transfer in the current case of deuterated 5

This combined experimental and theoretical study answers the question whether the intramolecular hydrogen-bond strength in amino alcohols is dependent on the ring size. For this purpose, the rotational spectrum of the 3-aminopropanol–H2O van der Wa

Rotational spectra were recorded for two isotopic species of two conformers of the amide derivative of leucine in the range of 10.5-21 GHz and fit to a rigid rotor Hamiltonian. Ab initio calculations at the MP2/6-311++G(d,p) level identified the low

The toxicity of emissions from the combustion of home heating oil coupled with the regional proximity and seasonal use of residential oil boilers (ROB) is an important public health concern. Yet scant physical and chemical information about the emiss

In this work, we develop a novel validation approach for studying how nonvolatile aerosol matrixes of considerably different chemical composition potentially affect the thermal extraction (TE)-GC/MS quantification of a wide range of trace semivolatil

This review examines thermal extraction gas chromatography-mass spectrometry (TE-GC-MS) applied to aerosols collected on filters. Several different TE-GC-MS systems as a group have speciated hundreds of individual organic constituents in ambient fine
