Infrared absorption spectrum of carbon disulfide.
The infrared absorption spectrum of carbon disulfide has been remeasured in the region from 2 to 24 I' with cells up to 5 mm in t hickness. Fifteen bands were observed , some however being of low intensity. The strongest band for the liquid occurs at 6.621' , and t he second harmonic of this band was observed at 2.22 1' , but t he first harm onic, which should be at about 3.33 1' , was not obse...
متن کاملInfrared absorption spectrum of the simplest Criegee intermediate CH2OO.
The Criegee intermediates are carbonyl oxides postulated to play key roles in the reactions of ozone with unsaturated hydrocarbons; these reactions constitute an important mechanism for the removal of unsaturated hydrocarbons and for the production of OH in the atmosphere. Here, we report the transient infrared (IR) absorption spectrum of the simplest Criegee intermediate CH2OO, produced from C...
متن کاملHigh-Resolution Observations of the Infrared Spectrum of Neutral Neon
We have observed the spectrum of neutral neon (Ne I) emitted by a microwave-excited electrodeless discharge lamp with the National Institute of Standards and Technology 2 m Fourier transform spectrometer. The spectra cover the regions 6929 Å to 11 000 Å with a resolution of 0.01 cm(-1) and 11 000 Å to 47 589 Å with a resolution of 0.007 cm(-1). We present a line list that includes more than 650...
متن کاملThe strange mid - infrared spectrum of M 31 : ISOCAM observations ?
We present observations of the mid-IR spectrum of 4 small regions of M 31. The spectrum of the central 3′ is characterized by a strong, broad unidentified emission band (UIB) at 11.3 μm while the other usual UIBs at 6.2, 7.7 and 8.6 μm are absent or very faint. We present a map of this area in the 11.3 μm band and compare it with optical and H i images. The spectra of two other regions are simi...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
