I was reading that exciting a hydrogen atom to a certain point will force lower energy electrons to jump temporarily to high-energy/valence states. These electrons immediately return to the lower energy state and in the process, emit an EM pulse at 2.45 Ghz while the process continues. It also emits visible light.
I also read that at a temperature of about 51 C(121 F), that a full liter of hydrogen will reach this state. There are other ways but this example is extremely straightforward.
Question: Does that mean that hydrogen excited in this way will begin emitting incoherent microwave EM frequencies? Can I use my home microwave leak-detector on beaker of heated hydrogen gas just plucked from electrolysis and get a reading? If I had a copper coil near, would I register a voltage/magnetic field?
I am scared to experiment as my last name is not Hindenburg but I see tons of applications for communications.
