We present $^{12}$CO(1--0) and $^{12}$CO(2--1) maps of the interactingSeyfert 2/LINER galaxy NGC 5953 obtained with the IRAM interferometer atresolutions of 2\farcs1 $\times$ 1\farcs4 and 1\farcs1 $\times$ 0\farcs7,respectively. The CO emission is distributed over a disk of diameter$\sim$16\arcsec ($\sim$2.2 kpc), within which are several, randomly distributedpeaks. The strongest peak does not coincide with the nucleus, but is insteadoffset from the center, $\sim2-3^{\prime\prime}$ ($\sim$340 pc) toward thewest/southwest. The kinematics of the molecular component are quite regular, asis typical of a rotating disk. We also compared the $^{12}$CO distribution ofNGC 5953 with observations at other wavelengths in order to study correlationsbetween different tracers of the interstellar medium. Using NIR images, wecomputed the gravity torques exerted by the stellar potential on the gas. Thetorques are predominantly positive in both $^{12}$CO(1--0) and $^{12}$CO(2--1),suggesting that gas is not flowing into the center, and less than 5% of the gasangular momentum is exchanged in each rotation. This comes from the regular andalmost axisymmetric total mass and gas distributions in the center of thegalaxy. In NGC 5953, the AGN is apparently not being actively fueled in thecurrent epoch.
