been investigated by nanosecond transient absorption spectroscopy, photoacoustic calorimetry, measurements of 1 O 2 quantum yields, and photochemical studies in solution. Both the lifetime (1.4 μs) and the energy (74-76 kcal mol -1 ) of the BNEN triplet reflect its exceptional conformational rigidity, which prohibits relaxation along the 3 (π,π * ) potential energy surface by twisting around the C=C
已经通过纳秒瞬态吸收光谱、光声量热法、1 O 2 量子产率的测量研究了双环 [4.3.0] 非 1 (6)-en-2-one (BNEN) 的最低激发三重态的性质,和溶液中的光化学研究。BNEN 三重态的寿命 (1.4 μs) 和能量 (74-76 kcal mol -1 ) 都反映了其特殊的构象刚性,这通过围绕 C= 扭转来阻止沿 3 (π,π * ) 势能面的弛豫C键
