Abstract:
Cinnamate derivatives are considered promising starting points for novel UV filters, using judiciously chosen substitutions on this scaffold to achieve a rational optimization of their properties. Here, we employ electron donating substituents to induce changes in the electronic density distribution of this scaffold and position them such that steric interactions are modulated. Applying high-resolution laser spectroscopic techniques on supersonically cooled compounds in combination with quantum chemical calculations has enabled us to obtain a fundamental understanding of how the electronic structure of ground and electronically excited states as well as their dynamics are affected by such substitutions.

NMR and Mass Spectroscopy of Carboxylic Acids
While α protons of carboxylic acids absorb at 2–2.5 ppm, β protons absorb further upfield.
Carboxylic acids are easily identified by dissolving them in deuterium oxide, which results in a rapid exchange of the acidic protons with deuterium. This leads to the...
