http://home.earthlink-dot-net/~jimlux/hv/insulgas.htm has those gases, as well

Lots of folks have built sparkgaps (although not necessarily for tc's) that
run in all manner of gases. Probably one of the most popular is hydrogen,
which has good thermal properties, and quenches quickly. An easy way to
make a hydrogen gap is to put some alcohol in the bottom of the container
for the gap, heat it slightly to vaporize the alcohol and force the air
out, then seal the container. The gap runs in alcohol vapor, which under
the effect of the spark dissociates to hydrogen, etc.
