Perspective: Tipping the scales - search for drifting constants from molecular spectra
Paul Jansen, Hendrick L. Bethlem, Wim Ubachs
Transitions in atoms and molecules provide an ideal test ground for constraining or detecting a possible variation of the fundamental constants of nature. In this Perspective, we r…
Rayleigh-Brillouin scattering profiles of air at different temperatures and pressures
Ziyu Gu, Benjamin Witschas, Willem van de Water +1
Rayleigh Brillouin (RB) scattering profiles for air have been recorded for the temperature range from 255 to 340 K and the pressure range from 640 to 3300 mbar, covering the condit…
Photodissociation of interstellar N2
Xiaohu Li, Alan N. Heays, Ruud Visser +4
Molecular nitrogen is one of the key species in the chemistry of interstellar clouds and protoplanetary disks and the partitioning of nitrogen between N and N2 controls the formati…
Methyl mercaptan (CH3SH) as a probe for variation
Paul Jansen, Li-Hong Xu, Isabelle Kleiner +2
Torsion-rotation transitions in molecules exhibiting hindered internal rotation possess enhanced sensitivities to a variation of the proton-to-electron mass ratio. This enhancement…
Temperature-dependent bulk viscosity of nitrogen gas determined from spontaneous Rayleigh-Brillouin scattering
Ziyu Gu, Wim Ubachs
Values for the bulk viscosity of molecular nitrogen gas (N2) were derived from spontaneous Rayleigh-Brillouin (RB) scattering at ultraviolet wavelengths (366.8 nm) and at a 90 degr…
Prospects for high-resolution microwave spectroscopy of methanol in a Stark-deflected molecular beam
Paul Jansen, Isabelle Kleiner, Congsen Meng +4
Recently, the extremely sensitive torsion-rotation transitions in methanol have been used to set a tight constraint on a possible variation of the proton-to-electron mass ratio ove…
