Calculate the mass of the deuteron given that the first line in the Lyman series of H lies at 82259.08 cm-1 whereas that of D lies at 82281.476 cm-1. Calculate the ratio of

ionization energies of H and D.

1 answer

The mass of the deuteron is 2.0141 amu (atomic mass units).

The ratio of ionization energies of H and D is 1.0011.
