Abstract
We have designed a controller circuit to be incorporated into a commercial step-scan Fourier transform spectrometer (Bruker IFS 88 FTS). Alternatively, time-resolved data may be acquired with a transient digitizer provided by the user. We have demonstrated the versatility of the controller with a Lecroy 9450A transient digitizer as the recorder in the time-resolved emission detection of the CH radical populated in the A2Δ state and in the absorption measurement of the ambient air. The controller, which may be conveniently coupled to any data acquisition system, makes the use of the FTS more flexible and less expensive. © 1999 Society for Applied Spectroscopy.
