Detection of Hydrogen Hydrogen is prevalent in the universe. Life in the universe is ultimately based on hydrogen. The electronic energy of a hydrogen atom is given by DeltaE(n_(1) rarr n)=-C(1//n_(1)^(2)-1//n_(1)^(2)) , relative to zero energy at infinite separation between the electron and the proton (n is the principle quantum number, and C is a constant). For detection of the DeltaE=(3 rarr 2) transition (656.3 nm in the Balmer series), the electron in the ground state of the hydrogen atom needs to be excited first to the absorption line in the starlight corresponding to the DeltaE=(1 rarr 2) transition.
