High-resolution double-resonance spectroscopy of 2v(3) ? v(3) transitions in SF(6).
نویسندگان
چکیده
We assign the 2v(3) ? v(3) absorption transitions seen in a double-resonance pump-probe experiment. We compare the observed frequencies with those derived by calculating the 2v(3) rovibrational energy levels, using spectroscopic constants resulting from a 3v(3) analysis. Some features in the multiple-photon v(3) absorption spectrum of SF(6) can be attributed to two-photon transitions to 2v(3).

We report the first observation of a non-dipole transition in an ultra-cold atomic vapor. We excite the 3P-4P electric quadrupole (E2) transition in Na confined in a Magneto-Optical Trap(MOT), and demonstrate its application to high-resolution spectroscopy by making the first measurement of the hyperfine structure of the 4P1/2 level and extracting the magnetic dipole constant A = 30.6 ± 0.1 MHz...
متن کاملSatellites of Xe transitions induced by infrared active vibrational modes of CF4 and C2F6 molecules.
Absorption and luminescence excitation spectra of Xe/CF(4) mixtures were studied in the vacuum UV region at high resolution using tunable synchrotron radiation. Pressure-broadened resonance bands and bands associated with dipole-forbidden states of the Xe atom due to collision-induced breakdown of the optical selection rules are reported. The spectra display in addition numerous satellite bands...
متن کاملPulsed Microwave Microwave Double Resonance Spectroscopy with Fourier Transform Technique
Recently we showed that microwave (MW) double resonance experiments can be performed with microwave Fourier transform (MWFT) techniques [1]. In our first experiments we used a continuous microwave (CW) pump radiation. One observation is that the transient emission signal in the presence of a CW p u m p radiation decays faster. This results in an additional line broadening, as can be seen in Fig...
متن کاملHigh-resolution MRS in the presence of field inhomogeneity via intermolecular double-quantum coherences on a 3-T whole-body scanner.
Signals from intermolecular double-quantum coherences (iDQCs) have been shown to be insensitive to macroscopic field inhomogeneities and thus enable acquisition of high- resolution MR spectroscopy in the presence of large inhomogeneous fields. In this paper, localized iDQC (1)H spectroscopy on a whole-body 3-T MR scanner is reported. Experiments with a brain metabolite phantom were performed to...

Simultaneous analysis of explosives to identify, determine the purity and eliminate environmental pollution requires rapid, simple and cheap methods. Spectrophotometries method (UV-Vis), high-field proton nuclear magnetic resonance (1H-NMR), Raman spectroscopy and near infrared (NIR) are common methods that are applicable in two ways of direct and indirect in simultaneous analysis. In this poin...
