摘要:

A digital software‐controlled back‐off system for probe lamp dc signal nullification has been designed and incorporated into a laser flash photolysis spectrometer. This method takes advantage of modern high‐speed operational amplifiers already employed in the detection circuitry and the dedicated small computer that runs the spectrometer. The determination ofI0, necessary for absorbance calculations, is inherent in the method.
