We present high-resolution archival Atacama Large Millimeter/submillimeterArray (ALMA) CO J=3-2 and J=6-5 and HCO+ J=4-3 observations and new CARMA COand 13CO J=1-0 observations of the luminous infrared galaxy NGC 1614. Thehigh-resolution maps show the previously identified ring-like structure whilethe CO J=3-2 map shows extended emission that traces the extended dustyfeatures. We combined these new observations with previously publishedSubmillimeter Array CO and 13CO J=2-1 observations to constrain the physicalconditions of the molecular gas at a resolution of 230 pc using a radiativetransfer code and a Bayesian likelihood analysis. At several positions aroundthe central ring-like structure, the molecular gas is cold (20-40 K) and dense(> 10^{3.0} cm^{-3}) . The only region that shows evidence of a secondmolecular gas component is the "hole" in the ring. The CO-to-13CO abundanceratio is found to be greater than 130, more than twice the local interstellarmedium value. We also measure the CO-to-H_{2} conversion factor, alpha_{CO}, torange from 0.9 to 1.5 M_sol (K km/s pc^{2})^{-1}.
