Abstract
Photochemical reactions of free radicals and ions in cryogenic films have been investigated using infrared absorption spectroscopy. The amorphous films are formed by vapor deposition of one or more reagents onto an optical window at 10-77 K. Reactive intermediates are generated by pulsed UV laser photolysis, and photochemical quantum yields for product formation are determined spectroscopically. Comparisons of our results with those in the gas or crystalline phases are useful for discerning reaction dynamics in amorphous solids. In this report, we discuss work in progress to investigate acid-catalyzed photoinitiation, oligomerization and polymerization of amorphous formaldehyde.
