The infra-red absorption spectrum of methane 12CH4 in the region of 3μ has been re-investigated with higher resolving power than has been used previously. A very complex system of overlapping vibration bands has been revealed. The rotational fine structure of these bands has been partially analyzed, particularly having regard to the Coriolis interactions which occur in this case. The corresponding absorption bands of 13CH4 have also been examined.
