DIRECT OBSERVATION OF ORTHO-PARA TRANSITIONS IN METHANE. 15 min.
Publisher:
Ohio State UniversityAbstract:
Ortho-para transitions have been observed directly in $CH_{4}$ for the first time. These normally forbidden transitions were observed in the ground electronic, ground vibrational, and J = 2 rotational state by combining a simple level-crossing technique with the conventional molecular beam magnetic-resonance method. It is shown how this spectrum can be used to measure, for certain tetrahedral molecules, the interaction constants which appear in the Zeeman, nuclear-hyperfine and rotational-distortion Hamiltonians.
