Ah, i didn't read the table properly... I see now that the only wavelengths examined were in the ultraviolet. My mistake. Looking at available uv lasers, i can go down to 255nm without too much of a problem. Can you help me find a cross section for a wavelength atleast that? If smaller is the...

And i just read that the smallest IR wavelength that can be absorbed by hydrogen is 823.5nm. I'm not really sure of the maths because I've never done the calculation myself, if you want to check it out it's here...

I haven't decided yet, something infrared would be best i think. I can get a tunable laser if need be

Thanks again SpectraCat I'm not really sure how to answer that question, maybe if i just tell you what I'm planning on doing with the information you can help me figure it out? Pretty much what i want to do is have a laser that works at a frequency that is well absorbed by hydrogen...

Thanks SpectraCat! Just a quick one, brace yourself, this question mught be a bit retarded... How do those tables work? I was hoping to find something like a list of constants associated with a list of frequencies. Here's the formula i was hoping to plug the values into: If= Io exp(-k(f)nx)...

I've been looking everywhere for information on the absorption spectra of molecular hydrogen. I need some pretty exact numbers. If anybody can point me in the right direction it would be greatly appreciated.
