- Two-dimensional infrared spectroscopy (2D IR) has proved to be very powerful in investigating fast dynamics of molecular complexes, especially, occurring in the picosecond time scales. In spite of its high capability, however, it has not been used so widely because of the technical difficulty in building a 2D IR apparatus. Hence, to construct a 2D IR apparatus is considered to be a meaningful scientific achievement because it can be the ground for future research. A 2D IR apparatus is composed of an optics (or mechanical) part and a data acquisition part. For a 2D IR apparatus to function properly the two parts should work in a cooperative way. For the 2D IR experimental system in this laboratory, a preexisting 2D IR data acquisition Application (DAA) was modified to control more number of devices effectively and eventually to perform advanced 2D IR experiments. With this improved DAA, 2D IR spectra of sodium azide in water (NaN3 in H2O) were successfully obtained. Generation of the improved DAA which is suitable for new type of 2D IR experiments is the main subject of this thesis and, the content of the improved DAA is described in detail.
