1926H. A. Spoehr Photosynthesis v. 285 They tried to detect the photoisomerization of the chlorophyll-carbonic acid complex. 1956H. A. Borthwick et al. in A. Hollaender Radiation Biol. III. x. 494 The relative biological response, such as internode elongation, seed germination, or flowering, is limited by the photoisomerization of the pigment. 1965Seliger & McElroy Light v. 305 When rhodopsin in the retina is exposed to white light, the result is a photoisomerization to the yellow-colored all-trans form through several intermediate steps. 1976H. Campion et al. in B. E. C. Nordin Calcium, Phosphate & Magnesium Metabolism xii. 452 Ergocalciferol itself can, under prolonged irradiation, undergo irreversible photoisomerization. So ˌphotoiˈsomerize v. intr., to undergo photoisomerization.
