We demonstrate here unambiguously that (E)-urocanic acid, an epidermal and photobiologically important chromophore, undergoes isomerization to the (Z) isomer upon excitation with UVA (320-400 nm) light using monochromatic 355 and 340 nm laser radiation. Additionally, chemical evidence is presented t
