Abstract

Complexes of organic molecules with the main component of earth’s atmosphere are of interest,footnote{Kuma, S., Slipchenko, M. N., Kuyanov, K. E., Momose, T., Vilesov, A. F., Infrared Spectra and Intensities of the H$_2$O and N$_2$ Complexes in the Range of the $nu_1$- and $nu_3$-Bands of Water, textit{J. Phys. Chem. A}, textbf{2006}, textit{110}, 10046--10052.} also for a stepwise understanding of the phenomenon of matrix isolation.footnote{Coussan, S., Bouteiller, Y., Perchard, J. P., Zheng, W. Q., Rotational Isomerism of_x000d_ Ethanol and Matrix Isolation Infrared Spectroscopy, textit{J. Phys. Chem. A}, textbf{1998}, textit{102}, 5789--5793.} Via its large quadrupole moment, nitrogen binds strongly to polarized OH groups in hydrogen-bonded dimers. Further complexation leads to a smooth spectral transition from free to embedded molecules which we probe in supersonic jets. Results for 1,1,1,3,3,3-hexafluoro-2-propanol,footnote{Suhm, M. A., Kollipost, F., Femtisecond single-mole infrared spectroscopy of molecular clusters, textit{Phys. Chem. Chem. Phys.}, textbf{2013}, textit{15}, 10702--10721.} methanol,footnote{Larsen, R. W., Zielke, P., Suhm, M. A., Hydrogen bonded OH stretching modes of methanol clusters: a combined IR and Raman isotopomer study, textit{J. Chem. Phys.}, textbf{2007}, textit{126}, 194307.} $t$-butyl alcohol,footnote{Zimmermann, D., Häber, T., Schaal, H., Suhm, M. A., Hydrogen bonded rings, chains and lassos: The case of $t$-butyl alcohol clusters, textit{Mol. Phys.}, textbf{2001}, textit{99}, 413--425.} and the conformationally more complex ethanolfootnote{Wassermann, T. N., Suhm, M. A., Ethanol Monomers and Dimers Revisited: A Raman Study of Conformational Preferences and Argon Nanocoating Effects, textit{J. Phys. Chem. A}, textbf{2010}, textit{114}, 8223--8233.} are presented and assigned with the help of quantum chemical calculations.
