High-spatial-resolution CO observations of galaxies have shown detailed distribution and dynamics of the molecular gas in spiral galaxies. We review observations, and show that the molecular gas distributions in the nuclear regions can be classified into three types: a core type with high concentration toward the nucleus; compact-ring type with ring radius of ∼200 pc; and a broad-ring type with ring radius of several hundred pc to ∼1 kpc. We also discuss their implications.
