Question about spectral emission measurements of hydrogen

[tpthorpejr]

Looking for typical experimental parameters for measuring emission spectrum of both H and H2, specifically gas pressures. Also would like to know typical pressure range where spectrum transitions from H2 to H. Thanks.

Welcome to PF;
Have you tried looking at the specs for laboratory hydrogen (and helium) discharge tubes?
You should be able to find a typical student rig in the nearest college teaching lab.

However, what counts as "typical" depends on the application.
