The acquisition of a femtosecond transient absorption spectrometer which is necessary to study and understand the dynamics of photoexcitation events on extremely short timescales, form femtosecond to nanosecond, is proposed. The instrument will provide the tools needed to investigate ultrafast phenomena in molecules and materials, and is required for ongoing research in fields as diverse as photophysics, photochemistry, photobiology, and photomedicine. The proposed equipment will be located at the Laboratory for Advanced Spectroscopy and Imaging Research (LASIR) in the Department of Chemistry at the University of British Columbia (UBC). LASIR is founded with CFI-funded infrastructure in 2006 and is now a shared user facility located at UBC and Simon Fraser University (SFU). LASIR provides services and access to many researchers within and outside the university, and has been a major factor in international collaborations. The facility is utilized by more than 60 principal investigators, and more than 150 undergraduate and graduate students, postdoctoral fellows and research associates. The femtosecond transient absorption spectrometer is urgently needed as many of the most important energy transfer processes and photochemical reactions occur on this time-scale and cannot currently be investigated due to the lack of this infrastructure.

飞秒瞬态吸收光谱仪的收购，这是必要的研究和理解的光激发事件的动力学在极短的时间尺度上，从飞秒到纳秒，提出。该仪器将提供研究分子和材料中超快现象所需的工具，并且需要在光物理学，光化学，光生物学和光医学等不同领域进行研究。 拟议的设备将设在不列颠哥伦比亚省（UBC）大学化学系高级光谱学和成像研究实验室（LASIR）。LASIR成立于2006年，由CFI资助的基础设施，现在是位于UBC和西蒙弗雷泽大学（SFU）的共享用户设施。LASIR为大学内外的许多研究人员提供服务和访问，并一直是国际合作的主要因素。该设施由60多名主要研究人员，150多名本科生和研究生，博士后研究员和研究助理使用。飞秒瞬态吸收光谱仪是迫切需要的，因为许多最重要的能量传递过程和光化学反应发生在这个时间尺度上，目前无法进行调查，由于缺乏这种基础设施。
