Research output: Contribution to journalArticlepeer-review


The photoisomerization of 1,1′-dimethoxyazobenzene was investigated. This compound has two big substituents at the ortho and ortho' positions which might interfere with the rotation around the ring-N single bond. Photochemical steady states were obtained by irradiation at various wavelengths. The composition of these steady states and the quantum yields were calculated. The unusual results at extremely low temperatures were related to the existence of conformational isomers.
