C-H Functionalization : A Holy Grail Transformation
Prusinowski, Allen ( 2020-02 )A double functionalization of vicinal sp3 C-H bonds has been developed, wherein a β amine and γ iodide are incorporated onto an aliphatic alcohol in a single operation. This approach is enabled by an imidate radical ... -
C-H STRETCH OVERTONE SPECTRA OF FLUORINATED ETHERS
Hsieh, Shizuka ( 2011 )Photoacoustic spectra of some fluorinated ethers at 4-6 quanta of C-H stretch illustrate effects of fluorination on overtone frequencies and intensities. -
THE C-H STRETCH SPECTRUM OF ETHYLENE IN LIQUID HELIUM DROPLETS
Lindsay, C. Michael; Lewis, William K.; Miller, R. E. ( 2003 )In this talk we report our study of $^{12}C_{2}H_{4}$ monomer and its clusters in $^{4}He$ with the new, ""second generation"" helium droplet/infrared spectroscopy apparatus at UNC. The region containing the $\nu_{11}$ and ... -
THE C-N STRETCHING VIBRONIC BANDS OF THE MgNC $\tilde{A} {^{2}}\Pi - \tilde{X}{^{2} \Sigma^{+}}$ TRANSITION
Fukushima, Masaru; Ishiwata, Takashi ( 2002 )We have generated MgNC in supersonic free jet expansions, and measured the laser induced fluorescence excitation spectra of the C-N stretching vibronic bands of the $\tilde{A}{^{2}}\Pi - \tilde{X}{^{2}}\Sigma^{+}$ transition. ... -
C-O AND O-H BOND ACTIVATION OF METHANOLE BY LANTHANUM
Silva, Ruchira; Hewage, Dilrukshi; Yang, Dong-Sheng ( 2012 )The interaction between methanol (CH$_3$OH) molecules and laser-vaporized La atoms resulted in the cleavage of C-O and O-H bonds and the formation of three major products, LaH$_2$O$_2$, LaCH$_4$O$_2$ and LaC$_2$H$_6$O$_2$, ... -
THE C-O STRETCHING BAND IN THE RAMAN SPECTRUM OF METHANOL: SOME EFFECTS OF ENVIRONMENT AND ASSOCIATION
Watson, Gary M.; Atalla, Rajai H. ( 1973 )The structure of the C-O stretching band in the Raman spectrum of $CH_{3}OH$ is sensitive to environment and associations. At lower concentrations of $CH_{3}OH$ (5 mole \% ) in $CCI_{4}, CS_{2}$, and $CHCI_{3}$, the band ... -

C. William O'Neill and the 1958 right-to-work amendment
Hissam, Michael B. ( 2005-06 )C. William O’Neill is the only person in Ohio’s history to serve at the top of all three branches of state government. In the course of a lengthy career, he suffered just one defeat at the polls. In 1958, O’Neill lost ... -
C...H...N HYDROGEN BOND FORMATION IN TRIMETHYLAMINE DIMER UPON ONE-PHOTON IONIZATION
Nakayama, Yuichiro; Matsuda, Yoshiyuki; Fujii, Asuka ( 2011 )Structures of trimethylamine dimer cluster cations which are generated by the vacuum-ultraviolet photoionization are investigated by a combination of infrared spectroscopic methods and theoretical reaction-pass calculations. ... -
$C^{-}_{7}$ AND THE DIFFUSE INTERSTELLAR BANDS
McCall, Benjamin J.; York, Donald G.; Oka, T. ( 1999 )The diffuse interstellar bands (DIBs) are a set of absorption features appearing in the visible spectra of stars whose lines of sight travese interstellar dust and gas. The identification of the carriers of these bands has ... -
$C^{13}$--NUCLEAR MAGNETIC SHIELDING IN AROMATIC COMPOUNDS
Spiesecke, H.; Schneider, W. G. ( 1960 )“The relative $C^{13}$ chemical shifts of some monosubstituted benzene derivatives have been measured. The assignments were made with the aid of the spectra of the 3,5-and 2,4,6-deuterated analogues. The most striking ...
