Observations of the C-18O(3-2) and 13CO(3-2) rotational transitions were obtained 9 Nov 2007 using the Submillimeter Array (SMA). In addition, the first detection of the C-18O(6-5) rotational transition, at 658.553 GHz, was made using SMA data from 14 Dec 2005. Preliminary measurements of the isotopic ratios 13C/12C and 18O/16O will be presented. Moreover, the Cassini mission provides updated 13C/12C and D/H ratios in CH4 and C2H2. Recently 13C/12C and 18O/16O ratios in CO2 are obtained, including both singly and doubly isotope substituted compounds. Incorporating laboratory measured rate coefficients in isotope-variant chemical reactions (both two-body and photolytic reactions) into a photochemical model, the profiles of C- 16O, C-18O, 13CO, C-16O-16O, C-16O-18O, 13C-16O-16O, 13C-16O-18O, CH4, 13CH4, CH3D, 13CH3D, C2H2, C2HD, C2H6, C2H5D, and other C2 hydrocarbons are obtained. Implications of the model results to the evolution and origin of Titan's atmosphere are discussed.
