Application Note 47 – [2+2] Photocycloaddition with wavelength specific low pressure mercury lamps

This application note uses the photochemical reaction explored in application note 36, the photocycloaddition of maleimide and 1-hexyne, to explore the performance of Vapourtec’s new low pressure mercury lamps. For this reaction the low pressure lamps are used in place of the
medium pressure lamp with filters. Three low pressure mercury lamps are tested, each with a specific and very narrow wavelength emission band.
