Measurement and assignment of 10 rotational energy levels in the 9510 to 9810 cm and 6590 to 6900 cm ranges of methane using optical frequency comb double-resonance spectroscopy

Yuan Cao, Adrian Hjältén, Vinicius Silva de Oliveira +4

Accurate models of high temperature methane spectra are needed in astrophysics. Previous measurements of methane hot-band transitions in the 6 2 polyad…

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…

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…
