The photostability of compounds (3)-(9) (Table 1) in the solid state is not due to any inherent electronic or steric properties of these molecules as they are all known to dimerize in solution. It must be attributed to an unfavourable arrange-ment of these molecules in the crystal lattices both in the macro-and micro-regions. The authors thank the U.G.C. and C.S.I.R. for support of this research. Received, 23rd March 1981: Corn. 323 References 1 J. M. Thomas, S. E. Morsi, and J. P. Desvergne, Adv. Phys. Org.

N2 - Photochemical dimerization of 7-methoxycoumarin occurs in the solid state to give high yields of a syn-head-to-tail dimer although the potentially reactive double bonds are not favourably oriented in the crystal of the monomer.
