摘要：

Aberchrome(TM) 540 is an easy actinometer to use in the range 310-370 nm. Nevertheless the photocyclization competes with a side reaction which leads to an underestimation of the light intensity when the actinometer is used repeatedly after bleaching. This side reaction is attributed to E half arrow right over half arrow left Z isomerization, whose photostationary equilibrium depends on the wavelength. It is suggested that the irradiated solution should not be reused after bleaching.
