Web5 jun. 2012 · In its atomic form in the ISM, it emits radiation at the radio frequency of 1420 MHz. The transition is between the two hyperfine states of the ground state. Their energy difference, and hence the frequency of the transition, arises from the interaction of the magnetic moments of the proton and electron constituting the atom. WebIt is straightforward to show that the rotational transition J = 1 to 0 of the CO molecule results in a spectral line at frequency 115.2712 GHz, while the J = 2 to 1 transition gives a line at 230.5424 GHz, given that the intermolecular bond distance is 1.128 A.
