E. ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (5MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) Two spectroscopic relational databases, denoted MeCaSDa and ECaSDa, have been implemented for methane and ethene, and included in VAMDC (Virtual Atomic and Molecular Data Centre, http://portal.vamdc.eu/vamdc\_portal/home.seam) ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (9MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) New data on the IR spectra induced by intermolecular interactions in liquid cryogenic mixtures at T=89 K (O$_{2}$in LAr and LN$_{2}$and binary O$_{2}$-Ar solutions in LN$_{2}$) are reported. \ The induced fundamental ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (2MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) Using an extended cavity diode laser locked to a frequency comb, the line shape of the P(11) line in the$\nu_1$+$\nu_3$combination band of acetylene has been studied as a function of varying concentration of the absorber ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (3MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) Precise and accurate positions of the line centers of HCl (v = 2$\leftarrow$0) have not been reported for quite some time$^1$, however, using methane as a transferrable standard, we aim to report line positions to an ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (6MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) The electronic spectrum of$^{130}\rm{Te}_{2}$serves as a frequency standard for many spectroscopic investigations. We scanned the molecule in the region 664 to 676 THz using a tunable diode laser to create an atlas of ... application/pdf PDF (2MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) \begin{wrapfigure}{r}{0pt} \includegraphics[scale=0.3]{cropped2.eps} \end{wrapfigure} We present comprehensive line lists of \chem{CH_4} at high temperatures for the pentad and octad region (2400--5000 \wn). These ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (11MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) As the simplest polyatomic molecule, H$_3^+$serves as an ideal benchmark for theoretical predictions of rovibrational energy levels. By strictly \textit{ab initio} methods, the current accuracy of theoretical predictions ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (3MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) A new line list for rovibrational and rotational transitions within the NH X$^3\Sigma\rm{^-}$ground state has been created, including line intensities in the form of Einstein \emph{A} and \emph{f}-values, for all possible ... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (4MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) To achieve NASA's strategic scientific mission of monitoring global atmospheric CO$_2$at a target precision of 0.25\%, we perform laser based measurements and lineshape studies of the reference atmospheric target CO$_2$... application/vnd.openxmlformats-officedocument.presentationml.presentation Microsoft PowerPoint 2007 (7MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) A precise, repeatable and stable optical frequency source is required for many modern spectroscopy experiments. Frequency combs have proven invaluable to many, but are not obtainable for others due to their high cost. Using ... application/pdf PDF (2MB) • (International Symposium on Molecular Spectroscopy, 2014-06-16) We present the results of prediction of energy levels of various water isotopologues using the fit of mass independent part of potential energy surface (PES) of H$_2^{16}\$O only. Fit was done in such a way that mass ...
