ETUDE DE L'EFFET D'UN MODIFICATEUR ORGANIQUE, POLAIRE, DU DIOXYDE DE CARBONE SUR LES DONNEES SPECTRALES INFRA-ROUGE. DANS UN DEUXIEME TEMPS, L'EFFET DE LA PHASE STATIONNAIRE CONSTITUEE PAR UN COPOLYMERE EST ANALYSE
Book Description
LA CHROMATOGRAPHIE EN PHASE SUPERCRITIQUE (CPS) PERMET, NON SEULEMENT LA SEPARATION DE COMPOSES NON VOLATILS ET/OU THERMOLABILES AVEC DE TRES HAUTES EFFICACITES MAIS AUSSI LE COUPLAGE AVEC DE NOMBREUX DETECTEURS DONT L'INFRAROUGE A TRANSFORMEE DE FOURIER. LE DIOXYDE DE CARBONE PRESENTE DE LARGES FENETRES DE TRANSPARENCE EN IR, MAIS CERTAINES VIBRATIONS SONT NON DETECTEES. LE MEILLEUR FLUIDE POUR LA CPS-IRTF EST LE XENON, MAIS EN RAISON DE SON FAIBLE POUVOIR ELUANT, SON UTILITE RESTE LIMITEE. POUR FAVORISER L'ELUTION DES PRODUITS POLAIRES, SOIT ON AJOUTE UNE FAIBLE QUANTITE DE MODIFICATEURS POLAIRES AU CO#2, CE QUI N'EST PAS SANS CONSEQUENCE SUR LA TRANSPARENCE IR DE LA PHASE MOBILE; SOIT ON UTILISE UNE PHASE STATIONNAIRE POLYMERE (PRP-1) SANS GROUPEMENT SILANOL. UNE ETUDE DU MECANISME DE RETENTION SUR UNE FAMILLE DE COUMARINES A PERMIS DE CONCLURE SUR LE TYPE D'INTERACTIONS MISES EN UVRE LORS DE L'ELUTION ET DE DEFINIR UNE ECHELLE ELUOTROPIQUE DIFFERENTE DE CELLE OBTENUE SUR C18. LE COUPLAGE CPS-IRTF A ETE APPLIQUE, EN PREMIER LIEU, A LA CARACTERISATION D'UN INTERMEDIAIRE REACTIONNEL INTERVENANT LORS DE LA CHLORATION DU TRICHLORO-2,4,6 PHENOL. LES PRINCIPAUX GROUPEMENTS FONCTIONNELS ONT ETE DEDUITS DE IRTF, ET LA STRUCTURE COMPLETE PAR LA SPECTROMETRIE DE MASSE (SM) ET LA RMN. DEUXIEMEMENT, LES SESQUITERPENES D'UNE HUILE ESSENTIELLE DE POIVRE ONT ETE IDENTIFIES GRACE A CETTE TECHNIQUE. APRES UN PREFRACTIONNEMENT PAR CHROMATOGRAPHIE LIQUIDE SEMI-PREPARATIVE, L'ANALYSE PAR CPS-IRTF AVEC DES MICROCOLONNES A PERMIS D'IDENTIFIER 42 CONSTITUANTS DE L'HUILE EN COMPLEMENTARITE AVEC LA SM

Book Description
The final and largest volume to complete this four-volume treatise is published in response to the intense commercial and research interest in Fourier Transform Interferometry.Presenting current information from leading experts in the field, Volume 4 introduces new information on, for example, applications of Diffuse Reflectance Spectroscopy in the Far-Infrared Region. The editors place emphasis on surface studies and address advances in Capillary Gas Chromatography - Fourier Transform Interferometry.Volume 4 especially benefits spectroscopists and physicists, as well as researchers in physical, analytical, and surface chemistry.FROM THE PREFACE: Several reasons can be cited for the need to publish Volume 4 in this treatise.First, interest in Fourier transform interferometry (FT-IR) has continued. The number of commercial manufacturers of FT-IR instrumentation has increased, reflecting the increase in demand for such instrumentation. The main thrust in FT-IR instrumentation has focused on applications, and many techniques using FT-IR instrumentation have been generated in order to solve problems heretofore unsolvable. The interest in surfaces relative to catalysts, polymers, and electrical conductors has escalated. Three chapters in Volume 4 are devoted to surfaces. Second, the great acceptance of Volumes 1 through 3 and the demand to continue the treatise have induced us to publish Volume 4.The present volume contains nine chapters, making it the largest of the four volumes. Chapter 1 deals with infrared data processing techniques. Chapter 2 concerns itself with circular dichroism*b1FT-IR. Chapter 3 presents an update on GC*b1FT-IR, a rapidly moving field. Chapter 4 deals with the combination of FT-IR and thermal analysis. Advances in coal analyses using FT-IR are presented in Chapter 5. Reflectance studies are highlighted in Chapters 6, 7, and 8. Chapter 6 deals with structural characterizations made with Langmuir*b1Blodgett monolayers. Also in Chapter 6, the extension of DRIFT into the far-infrared region is shown to be feasible and valuable. Reflection*b1absorption surface studies (FT-IRRAS) are discussed in Chapter 8. Chapter 9 updates us on photoacoustic spectroscopy*b1FT-IR.All of the contributions are made by working experts in these areas. It is the hope that Volume 4 continues in the spirit of the purpose of these volumes, namely, to keep the scientific communities abreast of new developments in FT-IR as applied to chemical systems.

Book Description
Practical Fourier Transform Infrared Spectroscopy: Industrial and Laboratory Chemical Analysis presents the Fourier Transform Infrared Spectroscopy (FT-IR) as a valuable analytic tool in solving industrial and laboratory chemical problems. The text provides chapters that deal with the various applications of FT-IR such as the characterization of organic and inorganic superconductors; the study of forensic materials such as controlled drug particles, fragments of polymers, textile fibers, and explosives; identification and quantification of impurities and measurement of epitaxial thickness in silicon; bulk and surface studies and microanalyses of industrial materials; and the identification or determination of unknown compounds. Chemists, industrial researchers, and product engineers will find the book useful.
