Abstract
Two double-resonance techniques have been used to confirm previously proposed assignments of infrared transitions in the CH318OH molecule. The techniques involve a cw CO2 laser, and they complement each other. The infrared–infrared double-resonance technique is used for probing accidental coincidences between the CO2 laser lines and Stark-tuned levels of E symmetry. Two such coincidences have been assigned, and the permanent electric dipole moment components μa″ and μa′ have been determined, for the first time to our knowledge, in this molecule for the ground state and the CO stretch state, respectively. The infrared radio-frequency double-resonance technique has been used to probe a level of A symmetry. This observation has permitted a more accurate determination of molecular asymmetry parameters with (n, K) = (0, 3) in both vibrational levels.
