Raising the benchmark potential of a simple alcohol-ketone intermolecular balance

Abstract

2-Butanone offers two hydrogen bond docking variants to a solvating methanol which are cleanly separated by supersonic jet infrared absorption spectroscopy in the OH-stretching range, resolving earlier action spectroscopy indeterminacies...

Subtle hydrogen bond preference and dual Franck–Condon activity – the interesting pairing of 2-naphthol with anisole

“…It is addressed by the concept of intermolecular energy balances, [14][15][16] where systems are picked for being ambivalent in terms of two different arrangements of their constituents. [17][18][19][20][21][22][23][24] The other aspect is the influence of molecular excitation of the components on this structural arrangement of the complex, due to the coupling of intramolecular degrees of freedom with intermolecular ones. This leads to the phenomenon of Franck-Condon effects in electronic and -less frequently observed in neutral complexes -vibrational spectroscopy of molecular aggregates.…”
