Optical frequency comb Fourier transform spectroscopy of formaldehyde in the 1250 to 1390 cm range: experimental line list and improved MARVEL analysis
Matthias Germann, Adrian Hjältén, Jonathan Tennyson +9
We use optical frequency comb Fourier transform spectroscopy to record high-resolution, low-pressure, room-temperature spectra of formaldehyde (HCO) in the range…
A methane line list with sub-MHz accuracy in the 1250 to 1380 cm-1 range from optical frequency comb Fourier transform spectroscopy
Matthias Germann, Adrian Hjältén, Vincent Boudon +6
We use a Fourier transform spectrometer based on a difference frequency generation optical frequency comb to measure high-resolution, low-pressure, room-temperature spectra of meth…
Optical Frequency Comb Fourier Transform Spectroscopy of NO at 7.8 μm
Adrian Hjältén, Matthias Germann, Karol Krzempek +5
We use a Fourier transform spectrometer based on a compact mid-infrared difference frequency generation comb source to perform broadband high-resolution measurements of nitrous oxi…
Fine- and hyperfine-structure effects in molecular photoionization: II. Resonance-enhanced multiphoton ionization and hyperfine-selective generation of molecular cations
Matthias Germann, Stefan Willitsch
Resonance-enhanced multiphoton ionization (REMPI) is a widely used technique for studying molecular photoionization and producing molecular cations for spectroscopy and dynamics st…
Fine- and hyperfine-structure effects in molecular photoionization: I. General theory and direct photoionization
Matthias Germann, Stefan Willitsch
We develop a model for predicting fine- and hyperfine intensities in the direct photoionization of molecules based on the separability of electron and nuclear spin states from vibr…
State-selected ion-molecule reactions with Coulomb-crystallized molecular ions in traps
Xin Tong, Tibor Nagy, Juvenal Yosa Reyes +3
State-selected Coulomb-crystallized molecular ions were employed for the first time in ion-molecule reaction studies using the prototypical charge-transfer process $\mathrm{N_2^++N…
