Optical frequency comb double-resonance spectroscopy of the 9030-9175 cm states of ethylene
Adrian Hjältén, Vinicius Silva de Oliveira, Yuan Cao +3
We use optical-optical double-resonance (OODR) spectroscopy to measure for the first time hot-band transitions of ethylene (CH) between states in the 3000 cm and…

Sub-Doppler optical-optical double-resonance spectroscopy using a cavity-enhanced frequency comb probe
Vinicius Silva de Oliveira, Isak Silander, Lucile Rutkowski +4
Accurate parameters of molecular hot-band transitions, i.e., those starting from vibrationally excited levels, are needed to accurately model high-temperature spectra in astrophysi…

Measurement and assignment of J = 5 to 9 rotational energy levels in the 9070-9370 cm range of methane using optical frequency comb double-resonance spectroscopy
Adrian Hjältén, Vinicius Silva de Oliveira, Isak Silander +6
We use optical-optical double-resonance (OODR) spectroscopy with a continuous wave (CW) pump and a cavity-enhanced frequency comb probe to measure high rotational energy levels of…
