Data acquisition interface for laser flash photolysis

可以使用传统设备监测以秒或更慢的时间尺度发生的化学反应。然而，许多反应发生的时间尺度非常快；例如，时间尺度比人眼眨眼快十亿倍。了解这些反应如何进行对于科学家能够以理性的方式改变它们至关重要。激光闪光光解（Lfp）是追踪快速反应的主要技术之一。反应性中间体通过激光照射形成，动力学随溶液吸收的变化而变化。 UVic 的系统于 1992 年实施，迫切需要新的数据采集接口。大多数检测硬件，如单色仪、延迟发生器和示波器都处于工作状态，但计算机和控制软件已经过时。如果计算机和接口出现故障，Lfp 系统将无法运行。持续接触 Lfp 实验对于 Bohne 小组在超分子动力学方面和 Wan 小组在机械有机光化学方面所做的工作至关重要，因为他们的学生的工作在很大程度上依赖于 Lfp 实验。

Chemical reactions that occur on time scales of seconds or slower can be monitored using conventional equipment. However, many reactions occur on very fast time scales; for example on time scales that are a billion times faster than the blinking of the human eye. Understanding how these reactions proceed is essential for scientists to be able to alter them in a rational fashion. Laser flash photolysis (Lfp) is one of the primary techniques to follow fast reactions. Reactive intermediates are formed by laser irradiation and the kinetics are followed by changes in the absorption of the solution. The system at UVic was implemented in 1992 and urgently needs a new data acquisition  interface. Most of the detection hardware, such as monochromators, delay generators and oscilloscopes are in working order, but the computer and control software are obsolete. In the case of failure of the computer and interface the Lfp system will not be functional. Continued access to Lfp experiments is essential for the work done in the Bohne group on supramolecular dynamics and in the Wan group on mechanistic organic photochemistry, since the work of their students relies heavily on lfp experiments.
