Simultaneous absorption of two photons prepared the excited states. Absorption of a third photon from the excited state generated the parent ions of methyl radical (m/z 15; CH3 and m/z 18; CD3) which were detected in a quadrupole mass spectrometer. The np 2A″2 Rydberg series was detected and identified by a rotational assignment of the 3p 2A″2 state of CD3 and by a polarization study of the np states. The quantum defect of this series was 0.6. The rotational constants determined for the ground and 3p 2A″2 excited states were B″0=4.798 cm−1 and B′0=4.768 cm−1. A vibrational analysis shows that both the symmetric stretch and out-of-plane bending mode are active in the 3p 2A″2 state. A second Rydberg series with a quantum defect of zero was detected and tentitively assigned to the nf 2E′ series.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319494635266","@type":"Researcher","foaf:name":[{"@value":"Jeffrey W.
