Molecules which have been buffer gas cooled

Although many species have been successfully buffer gas cooled, the limitations of the technique remain unknown.   We present here an incomplete, but ever growing list of polyatomic species that have been cooled in our group or elsewhere.  Our mixture analysis techniques rely on the idea that small molecules can be “universally” cooled in this technique. If we are missing yours let us know!
