Rotational energy levels in the ground vibrational state of methane with kHz-level accuracy from comb-referenced double-resonance and Lamb-dip spectroscopies
Vinicius Silva de Oliveira, Isak Silander, Hiroyuki Sasada +4
Methane is a key spherical-top molecule, yet restrictive selection rules for one-photon transitions have prevented determination of its ground state (GS) energies with state-of-the…

Ultra-broadband dual-comb spectroscopy across 1.0-1.9 μm
Sho Okubo, Kana Iwakuni, Hajime Inaba +4
We have carried out dual-comb spectroscopy and observed in a simultaneous acquisition a 140-THz-wide spectrum from 1.0 to 1.9 μm using two fiber-based frequency combs phase-locked…
