文摘

The rotational ground state distribution of H2 and D2 is determined via OES. The non-Boltzmann distributions can be described by a two-temperature distribution. It was demonstrated that the cold temperature reflects the gas temperature. No substantial difference between the isotopes H2 and D2 has been found.
