Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...

Photochemistry plays an important role in many chemical processes. Irradiating a sample with a suitable wavelength of light often results in free radicals, radical pairs, excited states, and changes ...

This study is led by Dr. Zhao-Yang Li (School of Material Science and Engineering, Nankai University) and Prof. Masahiro Yamashita (Department of Chemistry, Graduate School of Science, Tohoku ...

Electron Paramagnetic Resonance (EPR) spectroscopy is a form of magnetic resonance spectroscopy (MRS) that can be used to non-invasively detect impurities involved in the degradation of pharmaceutical ...
