    • Other devices for electronically measuring reaction quantum yields or fluorescence quantum yields have been described previously. However, each is significantly different from the radiometer described herein. For example, the system described by Baumann et al. [15] uses an excitation beam perpendicular to a monitoring beam from a UV-visible spectrophotometer instead of just one beam as used in our system. Furthermore, to our knowledge no system described in the literature uses a computer to control both the acquisition and the analysis of data. Finally, by using a commercial radiometer, our system is easily "constructed" by non-electronics experts. This feature in particular should make the present system exceedingly appealing to photochemists
