ABSTRACT

Introduction Diuse reectance laser ash photolysis and laser-induced luminescence, both in time-resolved mode or ground-state absorption spectroscopy in the diuse reectance mode, are important techniques that have been used by several research groups to study opaque and crystalline systems [1-8]. ese solid-state photochemical methods have been applied by us to study several organic compounds adsorbed onto dierent hosts such as microcrystalline cellulose [7, 8], p-tertbutylcalix[n]arenes (n = 4, 6, and 8) and their derivatives [10-12], silicalite, cyclodextrins [7, 12, 13], and silica [14].
