title: Triple-resonance spectroscopy on CH3OH far-infared laser lines.
abstract: Intracavity triple-resonance spectroscopy in CH(3)OH far-infrared lasers has been extended to the microwave region. A triple-resonance signal at 13410.45(10) MHz was observed on the 224.5-microm CH(3)OH laser line optically pumped by a waveguide CO(2) laser. The results confirm the assignment proposed for this line and improve the knowledge of A-state splitting in the = 5 vibrational state.
