Osaka, Japan – Getting a molecule to do what you want it to do is not always easy. As an example, an organic molecule will absorb only certain wavelengths of light based on its arrangement of ...

The spectrum of a substance — how it interacts with light — provides fundamental insight into its composition. A large number of molecules is typically required to obtain a detectable light-absorption ...

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

The team’s new compound can absorb electromagnetic waves in the NIR-II part of the spectrum, where waves can penetrate deeper into human tissue and generate heat, leading to photoacoustic emissions.

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This ...
