Abstract
The interaction between CH4 molecules shall be studied by neutron spectroscopic measurements for different phases of the substance. In a first investigation the molecular rotations are found to be completely free in the liquid state. A symmetrical splitting of the levelL=1 is observed. A comparison of the experimental results with transition probabilities calculated only from degrees of degeneracy gives good agreement for transitionsΔL≧2 and for those transitionsΔL=1 which haveL≧2 as the initial state. These transitions, therefore, appear to be rather independent ofL. The experiments indicate futhermore, that also with respect to their translational motions the molecules behave like in a gas.
