چکیده
The 3Vo}• and 4Vo}• of H20•, HNO3, and HO2NO2 have been observed. The band strengths o•f 3v_o• are (7.0 +1.8) x10 -2ø, (2.9 +0.7) x10 ©, and (3.8 +1.1) x10 -20 cm 2 moleculescmfor H20•, HNO3, and HO2NO9, respectively. Those of 4Vo• are (4.5 + 1.6) 21 21--71 2 1 1 x 10, (2.8 + 1.0) x 10, and (3.0 + 1.8) x 10cm moleculescmfor H202, HNO3, and HO2NO2, respectively. The uncertainty is for one standard eviation. Assuming excitation of these modes by solar absorption is dissociative for HO2NO2, these measurements confirm that this process will play a small role in the atmospheric photochemistry of the lower stratosphere.

Observational Constraints on the Oxidation of NOx in the Upper Troposphere.
NOx (NOx ≡ NO + NO2) regulates O3 and HOx (HOx ≡ OH + HO2) concentrations in the upper troposphere. In the laboratory, it is difficult to measure rates and branching ratios of the chemical reactions affecting NOx at the low temperatures and pressures characteristic of the upper troposphere, making direct measurements in the atmosphere especially useful. We report quasi-Lagrangian observations o...

Visible, near-infrared (NIR) and IR spectra in the 15600-2500 cm(-1) region were measured for phenol and 2,6-difluorophenol, 2,6-dichlorophenol, and 2,6-dibromophenol in n-hexane, CCl(4), CHCl(3) and CH(2)Cl(2) to study hydrogen bonding effects and solvent dependences of wavenumbers and absorption intensities of the fundamental and the first, second, and third overtones of OH stretching vibrati...
متن کاملThe observation of high order overtones and combinations in the SERRS spectra of a perylene dye spin coated onto silver island films.
The intensity of high harmonics and the background observed in the SERRS spectra of the bis(4-chlorbenzylimido)perylene (CLPTCD), spin-coated onto silver nanostructures are discussed. The SERRS spectra of an Ag island film spin coated with 50 microL of a 8.7 x 10(-7) M of CLPTCD in CH2Cl2 excited at 514.5 nm show signals from the first to the third overtones and combinations of fundamental vibr...

Reaction of [PtMe(C^N)(SMe2)] (C^N = 2-phenylpyridinate (ppy); 1a, C^N = benzo[h]quinolate, (bhq); 1b) with hydrogen peroxide gives the platinum(IV) complexes trans-[PtMe(OH)2(C^N)(H2O)] (C^N = ppy; 3a, C^N = bhq, 3b) bearing platinum-oxygen bonds. The Pt(II) complexes 1a and 1b have 5dπ(Pt)→π*(C^N) MLCT band in the visible region which is used to easily follow the kinetic of its reaction with ...

Introduction: Presence of external root resorption in second molars associated with impacted mandibular third molars was not rare. The neglect of this issue may leads to penetration of the pulp and loss of the second molars. The aim of this study was to investigate the incidence and risk factors affecting the external root resorption in second molars associated with mandibular impacted third mo...
