ABSTRACT:
An apparatus for investigating the course of fast chemical reactions in lid chemical systems, using optical detection and an external perturbation, especially by the temperature-jump method. The optical part of the apparatus comprises first and second light paths conveying a probing light beam and a sense light beam, respectively, and an optical lens system of extremely high aperture for measurements of absorption, fluorescence, and fluorescence polarization. The opto-electronic detection system comprises individual photodetector heads and a signal processing unit wherein special circuits for electronic division, zero-correction, large aperture error correction, and signal coupling eliminate disturbing signal components, reduce inherent errors of electronic signal processing, and simplify operation of the apparatus.
