摘要：

The dimerization reaction in crystals of 7-methoxycoumarin has been studied in the range 0-6 GPa using FT-IR high-pressure spectroscopy. Under UV irradiation the yield of the photodimer decreases linearly with pressure and at almost-equal-to 8 GPa the photoreaction is inhibited. Results are interpreted mainly in terms of non-topochemical dimers forming at defect sides of the crystal and rapidly propagating via the subsequent loss of order in the lattice.
