Optical frequency comb double-resonance spectroscopy of the 9030-9175 cm states of ethylene
This study utilizes optical-optical double-resonance spectroscopy with both frequency comb and continuous-wave probes to measure and assign hot-band transitions of ethylene between 3000 cm⁻¹ and 9000 cm⁻¹, providing improved center frequencies and tentative quantum assignments for numerous ladder-type and V-type transitions.
