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.
我们描述了一种改进的 NMR 探头，用于在溶液态 NMR 中进行光化学反应的原位辐照研究。为了建立这个装置，我们设计了一个辐照插件，将八个发光二极管（LED）置于 NMR 探头中，使其与样品非常接近。不同波长的 LED 插入件可以在几分钟内轻松更换。可调电源允许调整光强度以优化辐照条件。
