Photochemistry of Conjugated of a Chemical Compound Containing Three Double Bonds: Vitamin D Revisited |

Sarita Rani, in Journal of Advances in Science and Technology | Science & Technology


A survey is given ofvarious factors and conditions that affect the photoreactivity and photoproductdistribution of conjugated trienes, such as ground-state rotameric equilibrium,non-planarity of the chromophore, wavelength of irradiation, solvent andtemperature. The effect of changes in ground-state conformation and geometry,caused by substitution or variation of solvent or temperature, usually appearsto be more important and more easily predictable than excited state effects.
