Does the wavelength for photodissociation of hydrogen vary?

[Alan Boxx]

Photodissociation of hydrogen at ground state requires a 273nm wavelength for a photon particle to dissociate H²--> H^- + H⁺. But what about hydrogen at higher states of energy? Is the 273nm a constant? If not, what is the formula for min. wavelength for higher energy states (frequency-temperature relationship)? I've researched this quite a bit, but I can't find the answer I'm looking for.

Thanks a lot. I'll do my digging.
