Measurement and Assignment of Hot-Band Methane Transitions with Sub-MHz Accuracy

• We use double-resonance spectroscopy with cavity-enhanced comb probe to measure sub-Doppler transitions in the 3ν3←ν3 band of CH4. We assign the final states using different pump/probe combinations reaching the same state, and the dependence of line intensities on relative pump/probe polarization.
