Diffuse interstellar bands (DIBs) are ubiquitous absorption lines in the spectra of the reddened stars, which originate from foreground interstellar clouds. Although the carriers of most DIBs have not been successfully identified yet, they are considered to arise from the gas-phase carbonaceous molecules, such as fullerenes, polycyclic aromatic hydrocarbons (PAHs) and carbon-chain molecules [1]. The observational studies of DIBs may play an important role toward the understanding of the properties and chemistry of large organic molecules in interstellar medium.
