You can find some information on the refractive index at refractiveindex.info:

CO2:

https://refractiveindex.info/?shelf=main&book=CO2&page=Bideau-Mehu

https://refractiveindex.info/?shelf=main&book=CO2&page=Old

methane:

https://refractiveindex.info/?shelf=organic&book=methane&page=Rollefson

For ethane, this database only lists some ancient measurements for the visible range. Moreover, there is no information on the extinction coefficients available in the data base, but maybe you look up the original papers for some more information.
