碩士 === 國立交通大學 === 應用化學系碩博士班 === 104 === This thesis is consist of three main parts: 1.Bulid up a homemade time of flight (TOF) spectrometry. 2. Use abVIEW software to establish an automatic program. 3.Use the above instruments to measure the resonance-enhanced multiphoton ionization (REMPI) and pump-probe experiments. Part I: Build up a homemade TOF spectrometry with some special modules to improve the mass spectrometry resolution. By using Solidworks (a 3D CAD software) to simulate the process before assembly, we can prevent the instrument from interfering each other during assembly process. Part II: Use the LabVIEW software to code the automatic program to communicate the oscillator, laser, boxcar averager, and motorize translation stage. The automatic program can not only choose the mode between REMPI mode and pump-probe mode to execute the code but also monitor every instruments status. This automatic program can significantly shorten the time and reduce the manpower required to carry out the experiment. Part III: Applicate REMPI and pump-probe spectrum technique, with a homemade TOF spectrometry and automation integration program. We can get the REMPI spectrum of phenol, and the pump-probe spectrum of aniline.
