— All‐ trans ‐ and 13‐ cis ‐14,15‐dideuterioretinal were synthesized and their solution photochemistry examined. Quantum yields of trans → cis or cis → trans photoisomerization and the number and ratio of primary photoproducts, determined by high pressure liquid chromatographic analysis, are essentially identical to that of their corresponding retinal isomer. The C‐14, C‐15 carbon‐hydrogen modes play no particularly important role in the deactivation of electronically excited linear polyenes related to retinal.
