Constraining Inflation with the BICEP/Keck CMB Polarization Experiments Open
The BICEP/$\textit{Keck}$ (BK) series of cosmic microwave background (CMB) polarization experiments has, over the past decade and a half, produced a series of field-leading constraints on cosmic inflation via measurements of the "B-mode" p…

Supporting information for "Kinetics of CN(v=1) reactions with butadiene isomers at low temperature by cw-Cavity Ringdown in a pulsed Laval flow with theoretical modelling of rates and entrance channel branching Open
This file contains the master equation inputs for all the reactions studied, as well as all the details on stationary points and VRC-TST fluxes necessary to reproduce the simulations.

Kinetic study of the OH + ethylene reaction using frequency‐modulated laser absorption spectroscopy Open
The pressure dependence of the OH + C 2 H 4 addition reaction has been investigated using frequency‐modulated laser absorption spectroscopy to monitor OH kinetics. Bimolecular rate coefficients for the title reaction are reported in argon …

Anomalous Intensities in the 2+1 REMPI Spectrum of the E <sup>1</sup>Π–X <sup>1</sup>Σ<sup>+</sup> Transition of CO Open
We report on one-color experiments near 214 nm involving the photodissociation of jet-cooled OCS to produce high rotational states (40 < J < 80) of CO (X 1Σ+, v = 0, 1) which were then ionized by 2+1 resonance-enhanced multiphoton ionizati…

TIME- AND FREQUENCY-DOMAIN SIGNATURES OF VELOCITY CHANGING COLLISIONS IN SUB-DOPPLER SATURATION SPECTRA AND PRESSURE BROADENING Open
We have combined experimental and theoretical approaches to the competition between elastic and inelastic collisions of CN radicals with Ar, and how this competition influences time-resolved saturation spectra. Experimentally, we have meas…

Supercontinuum Fourier transform spectrometry with balanced detection on a single photodiode Open
We demonstrate a method of combining a supercontinuum light source with a commercial Fourier transform spectrometer, using a novel approach to dual-beam balanced detection, implemented with phase-sensitive detection on a single light detec…

The near-infrared spectrum of ethynyl radical Open
Transient diode laser absorption spectroscopy has been used to measure three strong vibronic bands in the near infrared spectrum of the C2H, ethynyl, radical not previously observed in the gas phase. The radical was produced by ultraviolet…

Rotational and angular distributions of NO products from NO-Rg (Rg = He, Ne, Ar) complex photodissociation Open
We present the results of an investigation into the rotational and angular distributions of the NO Ã state fragment following photodissociation of the NO-He, NO-Ne, and NO-Ar van der Waals complexes excited via the Ã←X̃ transition. For each…
