Nowadays, studies employing molecular modeling and
sunscreen agents are sometimes performed in order to evaluate
properties such as environmental photodegradation behavior
[24], UV–VIS simulation spectra of natural [9, 15, 25] and
synthetic products [17]. Therefore, our objectives were to
study the electronic structure as well as the excited states of
cinnamates, in order to understand the electronic mechanism
related to UVabsorption employing TD-DFT methods
