Abstract. The design and construction of a novel heated cuvette holder for fiber optic UV–vis spectrophotometers is described. The cuvette holder is especially useful for determining the kinetics of reactions at temperatures greater than 100 °C. Kinetics for the Diels–Alder reaction of tetraphenylcyclopentadienone with diphenylacetylene are investigated at several temperatures as an illustration of the benefits of the new system.
