The laser serves only in a secondary role for FT-IR spectroscopy, but as a source for excitation it has greatly revolutionized conventional Raman spectroscopy and led to the advent of new techniques including coherent anti-Stokes Raman scattering CARS , Raman gain, inverse or hyper- Raman spectroscopy. Both FT-IR and Raman techniques have also benefited from the improvements in optoelectronic and data processing systems. While a moving mirror with high mechanical precision and a high quality beam splitter are basic to an FT-IR instrument, a double monochromator with precision gratings, which may be holographic, and a laser as light source are intrinsic to a Raman spectrometer. Improved detector systems pyroelectric bolometers, such as triglycine sulfate, TGS, for FT-IR or photon counting for Raman , not available a decade ago now serve vital functions. Utilization of an on-line mini-computer is all but essential for practical FT-IR spectroscopy in order to facilitate the data handling and computation; it can also serve as a valuable accessory for the signal averaging and manipulation of Raman data.

Now in its third edition, this classic text covers many aspects of infrared and Raman spectroscopy that are critical to the chemist doing structural or compositional analysis. This work includes practical and theoretical approaches to spectral interpretation as well as a discussion of experimental techniques. Emphasis is given to group frequencies, which are studied in detailed discussions, extensive tables, and over carefully chosen and interpreted spectral examples. Also featured is a unique treatment of group frequencies that stresses their mechanical origin. This qualitative approach to vibrational analysis helps to simplify spectral interpretation.

Introduction to Infrared and Raman Spectroscopy focuses on the theoretical and experimental aspects of infrared and Raman spectroscopy, with emphasis on detailed group frequency correlations and their vibrational origin. Topics covered include vibrational and rotational spectra, molecular symmetry, methyl and methylene groups, triple bonds and cumulated double bonds, and olefin groups. Aromatic and heteroaromatic rings are also considered, along with carbonyl compounds and molecular vibrations. This book is comprised of 14 chapters and begins with a discussion on the use of Raman and infrared spectroscopy to study the vibrational and rotational frequencies of molecules, paying particular attention to photon energy and degrees of freedom of molecular motion. The quantum mechanical harmonic oscillator and the anharmonic oscillator are described.

Organic Spectroscopy pp Cite as. Infrared spectroscopy deals with the recording of the absorption of radiations in the infrared region of the electromagnetic spectrum. Note that wavenumbers are often called frequencies, although strictly it is incorrect.

Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся. Беккер изо всех сил цеплялся за жизнь. Мотоцикл, виляя, мчался по газону и, обогнув угол здания, выехал на шоссе. Халохот, кипя от злости, побежал к такси. Несколько мгновений спустя водитель уже лежал на земле, с изумлением глядя, как его машина исчезает в облаке пыли и выхлопных газов. ГЛАВА 82 Когда мысль о последствиях звонка Стратмора в службу безопасности дошла до сознания Грега Хейла, его окатила парализующая волна паники. Агенты сейчас будут .

 Gratis? - по-прежнему увещевал бармен.  - За счет заведения. Превозмогая шум в голове, Беккер представил себе грязные улицы Трианы, удушающую жару, безнадежные поиски в долгой нескончаемой ночи. Какого черта. Он кивнул. - Si, echame un poco de vodka.

Вызовите мне машину. Мужчина достал мобильник, сказал несколько слов и выключил телефон. - Veinte minutos, - сказал. -Двадцать минут? - переспросил Беккер.  - Yel autobus. Охранник пожал плечами.
