Abstract

We describe a modified NMR probe for the in situ irradiation studies of photochemical reactions in solution-state NMR. To build up this setup, we designed an irradiation insert that brings eight light-emitting diodes (LEDs) into the NMR probe in the immediate proximity of the sample. The inserts with LEDs of different wavelengths are easily exchangeable within minutes. A tunable power supply allows to adjust the light intensity to optimize the irradiation conditions.
