A commercial scanning double-beam spectrophotometer [1] was extended at little cost to a combined measuring and irradiating device for the kinetic examination of photochemical reactions. The advantages in comparison to an earlier used single beam instrument [5] are: Simultaneous registration of the total absorption spectrum and digital acquisition of the absorbancy at selected wavelengths, a larger number of measuring points during reaction procedure, off-line data sampling, and shorter interruption periods of irradiation during measurement because of reduced data acquisition time. Two examples prove the high accuracy and the extended area of application. |
