In this manuscript we use a very high spatial resolution CO (J = 6-5) data from Atacama Large Millimeter/Sub-millimeter Array (ALMA) focused to the center region of Arp 220, at distance D = 77.4 Mpc (1 arcsecond = 375 parsec). The CO emission is resolved efficiently by ALMA beam (0.43"x 0.26"). We use long-slit along different direction of our sample to study the kinematic properties of the warm molecular gas within the inner region of Arp 220. We find the observed position-velocity (PV) diagram for this galaxy from its emission line. The major part of the molecular gas in Arp 220 was located mainly in the east and west nucleus. We measure 0.23 × 1010 M dynamical mass in the central of this galaxy. © Published under licence by IOP Publishing Ltd.
