The infrared absorption of HCl and HBr in solid nitrogen at liquid helium temperatures has been recorded. Multiplets have been observed in the region of the fundamental of each molecule. An interpretation is given, based on rotation of the HCl and HBr molecules in the nitrogen matrix.

Good Agreement

Within finite temperature Density Functional Theory, we have calculated the energy of the transitions from the ground state to the first two excited states in the electron bubbles in liquid helium at pressures from zero to about the solidification pressure. For 4 He at low temperatures, our results are in very good agreement with infrared absorption experiments. We have found that the 1s – 2p transition energies are sensitive not only to the size of the electron bubble, but also to its surface thickness. We also present results for the infrared transitions in the case of liquid 3 He .
