Molecular beam Fourier transform microwave spectrum of the dimethylether–xenon complex: tunnelling splitting and 131Xe quadrupole coupling constants

Isotopomeric Conformational Change in Anisole–Water

“…[20] He at a pressure of % 2 bar was blown over a 1:1 (v/v) mixture of water and anisole, and out through the solenoid valve (general valve, series 9, nozzle diameter 0.5 mm) into the Fabry-PØrot cavity, where the mixture reached an estimated rotational temperature of 1-2 K. The frequencies were determined after Fourier transformation of the 8k-data-point time-domain signal, recorded with 100-ns sample intervals. Each rotational transition was split by the Doppler effect as a result of the coaxial arrangement of the supersonic jet and resonator axes.…”

Lone‐Pair⋅⋅⋅π Interaction: A Rotational Study of the Chlorotrifluoroethylene–Water Adduct

“…Details of the Fouriertransform MW [26] spectrometer (COBRA-type [27] ), which covers the range of 6.5-18 GHz, have been described previously. [28] A gas mixture of about 1 % of chlorotrifluoroethylene (commercial sample used without further purification) in He at a stagnation pressure of about 0.25 MPa was passed over a sample of H 2 O and expanded through a solenoid valve (General Valve, Series 9, nozzle diameter 0.5 mm) into the Fabry-PØrot cavity. The spectral line positions were determined after Fourier transformation of the timedomain signal with 8k data points, recorded with 100 ns sample intervals.…”

Dynamical Behavior and Dipole–Dipole Interactions of Tetrafluoromethane–Water

“…[27] It was recently updated with the FTMW + + set of programs. [28] A mixture of 2 % in pressure CF 4 in He was flown over water at room temperature, and expanded to about 10 À5 mbar.…”
