测得HR578的初级光反应量子产率为0.34±0.0 2，光化学反应的量子产率为0.0 1±0.004。从稳态光照和闪光光解实验中，对HRL410的形成和衰变进行了定量描述，得到了一个孤立的、光适应的HR的光循环模型。这个模型满足关于HR的所有已知事实，包括它的光致变色行为。
The quantum yield of the primary photoreaction of HR578 was determined as øgreen = 0.34±0.02 and that of the photochemical reconversion of HRL410 into HR578 as øblue = 0.01±0.004. From steady‐state illumination and flash‐photolysis experiments, a quantitative description of HRL410 formation and decay was made leading to a model of the photocycle in isolated, light‐adapted HR. This model satisfies all known facts about HR including its photochromic behaviour.
