Abstract :
We report the detection of 13CH3D in Titanʹs stratosphere from Cassini/CIRS infrared spectra near 8.7 μm. Fitting simultaneously the ν 6 bands of both 13CH3D and 12CH3D and the ν 4 band of CH4, we derive a D/H ratio equal to 1.32 −0.11 +0.15 × 10 −4 and a 12C/13C ratio in deuterated methane of 82 −18 +27 , consistent with that measured in normal methane.
