摘要：

A new method to study transients in the microsecond region was developed. It utilizes spatial separation of excitation and probing by employing a fast-flowing jet stream. For excitation a cw laser is used. The time resolution is determined by the flow velocity and the focal diameter of the laser beam. Since excitation is not by way of short pulses, noise is low. Absorbance changes < 10(-4) could be detected even in the presence of intense fluorescence. The triplet parameters of rhodamine 6G and related laser dyes have been determined in ethylene glycol.
