本文主要研究分子间O - h···O氢键分子团簇的振动动力学。为此，在超音速射流膨胀中产生星团，并通过FTIR光谱在不同的光谱区域进行探测。
This work focuses on the vibrational dynamics of molecular clusters featuring intermolecular O–H···O hydrogen bonds. For this purpose the clusters are generated in supersonic jet expansions and probed via FTIR spectroscopy in different spectral regions.
The dimers of simple diols are characterized in the O–H stretching region. The O–H stretching overtones of the dimers of methanol, ethanol, tert-butyl alcohol and hexafluoroisopropanol are observed in the near infrared and anharmonicity constants are deduced. The librational vibration of the O–H group can be found in the far infrared and is observed for clusters of methanol, tert-butyl alcohol, trifluoroethanol and methyl lactate and partly for their deuterated isotopologues. The cold absorption spectrum of formic acid dimer and its deuterated isotopologues is characterized in the region from 200 to 1900 cm -1 . Fundamental transitions and some combination tones are assigned for the species.
