Infrared Absorption Spectra of Organic Sulfur Compounds. IV. : Studies on Characteristic Absorption Bands of o-, m-, and p-Substituted Benzenesulfonamide Derivatives

Absorption Spectra Studies on Cholesterol and Ergosterol.*

In the previous paper it was shown that highly purified spinal cord cholesterol is still activatable to antirachitic activity when irradiated in the solid form by a Cooper Hewitt mercury vapor quartz lamp. Although the activatability is decreased by the purification methods employed, nevertheless these purified products can again be rendered at least 25 times more activatable if heated under th...

Infrared Absorption Spectra of Steroids (an Atlas)

comments (p. 82), "Apr's de publications initiales optimistes, ont succede des rapports negatifs." In the introduction, it becomes clear that French laboratory methods are much like ours. The Lee-White method and the Quick test are standard procedures. On the other hand, the Continental workers seem to place more emphasis than we do on the in vitro heparin tolerance. Later portions of the book ...

Two-photon absorption spectra of carotenoids compounds

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...

Quantum-Chemical and Solvatochromic analysis of solvent effects on the Electronic Absorption Spectra of Some Benzodiazepine Derivatives

ABSTRACT The solvatochromic behaviour of two ketonic derivatives of benzodiazepine namely 7-chloro-1-methyl-5-phenyl-1,5-benzodiazepine-2,4-dione (Clobazam®) and 5,(2-chlorophenyl)-7-nitro-2,3-dihydro-1,4-benzodiazepine-2-one (Clonazepam®) were analysed in some selected solvents of different polarities using UV-Visible spectroscopy and DFT computational techniques. The solute-solvent interacti...
