Direct laser excitation in benzene of 1,8-dihydroxy-9-anthrone (anthralin) does not lead to transient species with lifetimes in the nanosecond time regime or longer. The triplet state has been produced in benzene by pulse radiolysis and characterised in terms of its absorption spectrum (lambda max 560 nm), natural lifetime (11 microseconds), self-quenching properties (kmicrosecond = 2.6 x 10(7) l mol-1 s-1) and triplet energy (234 kJ mol-1). There is no tendency in the non-polar medium for production of either the triplet or ground state in a tautomeric form. The observed triplet state reacts with oxygen with a typical rate constant, 2.2 x 10(9) l mol-1 s-1. The products of this reaction are singlet oxygen (approximately 64%) and the anthralin radical (approximately 14%).
在苯中对1,8 - 二羟基 - 9 - 蒽酮（蒽林）进行直接激光激发，不会产生寿命在纳秒时间范围或更长的瞬态物种。通过脉冲辐解在苯中产生了三重态，并根据其吸收光谱（λmax 560 nm）、自然寿命（11微秒）、自猝灭特性（k微秒 = 2.6×10⁷ l·mol⁻¹·s⁻¹）和三重态能量（234 kJ·mol⁻¹）对其进行了表征。在非极性介质中，不存在以互变异构形式产生三重态或基态的趋势。观察到的三重态与氧气反应，典型速率常数为2.2×10⁹ l·mol⁻¹·s⁻¹。该反应的产物是单线态氧（约64%）和蒽林自由基（约14%）。
