Results show that intramolecular hydrogen transfer is not favored in view of the energy trend along IHT coordinate in the region such as hypericin's peri region, where two hydrogens of hydroxyl groups bond with a common oxygen of carbonyl group and exists two IHBs in the peri region. However, intramolecular proton transfer often occur in the molecule with hexahydric cycle hydrogen bond, where only one pair of adjacent hydroxyl group and carbonyl group.

此外选择设计了一个具有三个分子内氢键的体系，兼具金丝桃蒽酮和其他苝醌类光敏剂的分子内氢键特点，研究表明两个羟基氢与共同的羰基氧形成的氢键由于存在较高的势垒，很难发生分子内氢传递，即具有金丝桃蒽酮端位结构的分子其分子内氢传递很难发生，而一般的能形成六元环状结构的分子内氢键体系容易发生分子内氢传递。
