Tunnelling dominates the reactions of hydrogen atoms with unsaturated alcohols and aldehydes in the dense medium [PDF]
, 2018 Hydrogen addition and abstraction reactions play an important role as surface reactions in the buildup of complex organic molecules in the dense interstellar medium. Addition reactions allow unsaturated bonds to be fully hydrogenated, while abstraction reactions recreate radicals that may undergo radical-radical recombination reactions.

Millimeter and Submillimeter Wave Spectroscopy of Propanal [PDF]
J. Mol. Spectroscc. 342 (2017) 125-131, 2017 The rotational spectra of the two stable conformers syn- and gauche-propanal (CH$_3$CH$_2$CHO) were studied in the millimeter and submillimeter wave regions from 75 to 500 GHz with the Cologne (Sub-)Millimeter wave Spectrometer. Furthermore, the first excited states associated with the aldehyde torsion and with the methyl torsion, respectively, of the $

Journal of the American Chemical Society, 2017 Umpolung (polarity reversal) strategies of aldehydes and imines have dramatically expanded the scope of carbonyl and iminyl chemistry by facilitating reactions with non-nucleophilic reagents. Herein, we report the first visible light photoredox-catalyzed

Unexpected composition dependence of the first sharp diffraction peak in an alcohol-aldehyde liquid mixture: n-pentanol and pentanal [PDF]
Physica Status Solidi B 255 (2018) 1800130, 2018 The total scattering structure factors of pure liquid n-pentanol, pentanal, and 5 of their mixtures, as determined by high energy synchrotron X-ray diffraction experiments, are presented. For the interpretation of measured data, molecular dynamics computer simulations are performed, utilizing 'all-atom' type force fields.
