抄録（英）
Comets are thought to be remnants of the planetesimals in the proto-planetary disk so that cometary ices provide us with precious clues of physical and chemical conditions in the early solar system. The mid-IR region is a very fruitful window to study the cometary volatiles since numerous ro-vibronic bands of molecules are observed simultaneously, and symmetric molecules can be accessed. However, because of the strong atmospheric extinction and the capability of previous instruments, there are only a few studies of cometary molecules in mid-IR regions with discontinuous limited wavelength regions or with low-dispersion spectroscopy. The mid-IR high-dispersion spectroscopy with SPICA could make a breakthrough discovery in the cometary volatiles like aliphatic hydrocarbons (e.g., C2H2, C2H4, C2H6), PAHs as well as the pre-biotic molecules (e.g., PH3). In this study, we discuss the feasibility to find new molecular species and to identify previously unidentified emission lines and the composition of those new species.
