## Description

 Title: Effect Of Substituents In Alcohol-amine Complexes Author(s): Hansen, Anne Schou Contributor(s): Kjærgaard, Henrik; Du, Lin Subject(s): Clusters/Complexes Abstract: \noindent A series of alcohol-amine complexes have been investigated to gain physical insight into the effect on the hydrogen bond strength as different substituents are attached. The series of complexes investigated are shown in the figure, \begin{wrapfigure}{o}{0pt} \includegraphics[scale=0.8]{structure-al-amine1.eps} \end{wrapfigure} \noindent where R$_1$ = CH$_3$, CH$_3$CH$_2$ or CF$_3$CH$_2$ and R$_2$ = H or CH$_3$. To estimate the hydrogen bond strength, redshifts of the OH-stretching transition frequency upon complexation were measured using gas phase Fourier Transform InfraRed (FTIR) spectroscopy. Equilibrium constants for the formation of the complexes were also determined, exploiting a combination of a calculated oscillator strength and the measured integrated absorbance of the fundamental OH-stretching and second overtone NH-stretching transitions.
