Infrared Spectra of Deuterium Compounds. I

Maximum Common Substructures of Organic Compounds Exhibiting Similar Infrared Spectra

Information about the unknown chemical structure of an organic compound can be obtained by comparing the infrared spectrum with the spectra of a spectral library. The resulting hitlist contains compounds exhibiting the most similar spectra. A method based on the maximum common substructure concept has been developed for an automatic extraction of common structural features from the hitlist stru...

Comments on the Interpretation of Dynamic Deuterium NMR Spectra from Solid Inclusion Compounds

Guest molecules trapped within the regular voids of crystalline adducts, called inclusion compounds, are likely to experience mobility. Recent solid-state *H NMR studies indicated these motions to be primarily discrete jumps related to the molecular symmetry, to that of the environment, or to some other geometric feature of the system investigated. In this work we offer a more consistent pictur...

The Far-Infrared Spectrum of Deuterium Iodide.

We recently described an investigation of the far-infrared (FIR) spectrum of hydrogen iodide, HI, which resulted in an accurate set of rotational and I electric quadrupole parameters for the molecule in its XS (v 5 0) state (1). In this Note, we report an extension of this work to the deuterated form of the molecule, DI. The spectrum of deuterium iodide was recorded using the third-order tunabl...

SPITZER MID-INFRARED SPECTROSCOPY OF INFRARED LUMINOUS GALAXIES AT z 2. I. THE SPECTRA

We present the mid-infrared spectra obtained with the Spitzer IRS for 52 sources, selected as infrared luminous, zk1 candidates in the Extragalactic First Look Survey. The sample selection criteria are f24 mk 0:9 mJy, f (24 m)/ f (8 m)k 3:16, and f (24 m)/ f (0:7 m)k10. Of the 52 spectra, 47 (90%) produced measurable redshifts based solely on the mid-IR spectral features, with 35/47 (74%) at 1:...
