二聚体

On the basis of the photoreactivity, spectroscopy, and spectrometry data, we determined the structure of the new photoproduct to be a nonadjacent cis-anti cyclobutane dimer formed between T2 and T7 with the absolute stereochemistry depicted by structure I (Figure 8B).

结论根据photoreactivity、分光学和光谱数据，我们确定新的photoproduct的结构是nonadjacent同边反cyclobutane二聚体被形成在T2和T7之间以结构描述的绝对立体化学I (图8B)。
