Infrared Spectra of Organic Titanium Compounds Containing both Alkoxy and Chelating Groups

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...

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 ...

Large and frequently occurring substructures in organic compounds obtained by library search of infrared spectra

Comparing the infrared spectrum of a compound whose chemical structure is unknown with the spectra of a library is a routinely used method to obtain information about the unknown structure. The resulting hitlist contains compounds exhibiting the most similar spectra. If the unknown is not contained in the library, a method based on the maximum common substructure concept can be applied to extra...

ATR spectra database of organic compounds

A spectral database of 100 attenuated total reflectance Fourier transform infrared spectra is created. The software IRSS previously developed in our lab is used to perform spectral search in the database. Despite the slight difference between the absorption and ATR FT-IR spectra, the comprehensive test search sessions of ATR spectra in IR libraries and vice versa (absorption spectra searched in...
