The distinct change in the magnetic susceptibility value of cinnamylidenmalonic acid and thiophosgene observed on exposure to light has been ascribed to the formation of a polymer and that of o-nitrobenzaldehyde to the formation of an isomer. [...] On the basis of the magnetic data obtained the view of Seine' and Shepherd that the change in colour of anils and hydrazones on exposure to light is due to the change in the aggregation has been favoured and other theories put forth to account for the mechanism of phototropy have been discussed. [...] It was found in all the cases that the magnetic susceptibility value of the compound after the recovery of the colour of the exposed sample was almost identical with the original one. [...] 1936 32 219) in the case of the polymerisation of cyclopentadiene where too the diappearance of the double bonds and the formation of the ring results in a fall rather than in a rise of mass susceptibility.678 S.

HASIIMI This conclusion is however open to the criticism that the above noted constancy in the value of the magnetic susceptibility on exPosure to light may be due to the formation of a mere trace of the compound B under the circumstances.
