Rotational spectrum, structure and modeling of the OCS–CS₂van der Waals dimer

Infrared spectra of rare gas–carbon disulfide complexes: He–CS2, Ne–CS2, and Ar–CS2

“…In the case of OCS-CS 2 the planar slipped near-parallel structure determined by Newby et al [9] was essentially the same as that of OCS-CO 2 [10]. But even here it turns out that there is a difference, since a higher-energy cross-shaped isomer of OCS-CS 2 has now been detected [11] which has no counterpart for OCS-CO 2 .…”

Reduced bandwidth chirped-pulse microwave spectroscopy for analysis of weakly bound dimers: Rotational spectrum and structural analysis of CH2ClF⋯FHCCH2

“…Kisiel's AABS software [35] was then used in conjunction with Pickett's SPFIT/ SPCAT package [36] to assign the spectrum. Once an initial assignment had been made using the CP-FTMW spectrometer, additional transitions were measured using a Balle-Flygare resonant cavity FTMW spectrometer at EIU [37,38]. The 37 Cl isotopologue spectrum was also visible in the CP-FTMW spectrometer scan, despite relatively low intensity for the dimer transitions in the broadband scan.…”

Rotational spectrum of three conformers of 3,3-difluoropentane: Construction of a 480MHz bandwidth chirped-pulse Fourier-transform microwave spectrometer

“…Numerous improvements can almost certainly be made in terms of optimizing the sample and timing conditions and these are currently being explored. Additional spectral measurements of 13 C isotopologues and Stark effect measurements were carried out in this study using a standard Balle-Flygare type resonant cavity instrument [4,12] although initial assignments of all spectra, including those of the 13 C species (observed in natural abundance), were made with the CP-FTMW spectrometer. Stark effect measurements were carried out by application of voltages up to ±5 kV to a pair of steel mesh plates placed 31 cm apart in the resonant cavity instrument's vacuum chamber, straddling the molecular expansion; electric field calibration was achieved by measurement of the J = 1 0 transition of OCS and assuming a dipole moment of 0.71519(3) D [13].…”

Field strengths up to 330 V cm À1 were used leading to Stark shifts of up to 1 MHz.…”
