The quantum yield of the primary photoprocess in light-adapted bacteriorhodopsin (phi 1) was determined at room temperature with low-intensity 530 nm neodymium laser excitation, with bovine rhodopsin as a relative actinometer. The observed value of phi 1 - 0.25 +/- 0.05, and the previously determined parameter phi 1/phi 2 - 0.4 [where phi 2 denotes the quantum efficiency of the back photoprecess from the primary species K (590)] imply that phi 1 + phi 2 approximately equal 1. This feature, also characterizing the photochemistry of rhodopsin, bears on the nature and mechanism of the primary event in both systems.
在室温下，以牛视紫红质作为相对光量计，用低强度530nm钕激光激发，测定了光适应细菌视紫红质初级光过程的量子产率（φ1）。观察到的φ1值为0.25±0.05，先前测定的参数φ1/φ2为0.4[其中φ2表示从初级物种K（590）的反向光过程的量子效率]，这意味着φ1+φ2约等于1。这一特征也是视紫红质光化学的特征，与两个系统中初级事件的性质和机制有关。
