Elle est id\u00e9ale pour les processus d\u2019identification et de quantification des \u00e9chantillons.   La spectroscopie Raman consiste \u00e0 diriger une source de lumi\u00e8re monochromatique \u2014 g\u00e9n\u00e9ralement un laser \u2014 sur un \u00e9chantillon et \u00e0 d\u00e9tecter la lumi\u00e8re diffus\u00e9e. La majeure partie de la lumi\u00e8re diffus\u00e9e pr\u00e9sente la m\u00eame fr\u00e9quence que la source d\u2019excitation et ne fournit pas d\u2019informations utiles ; ce ph\u00e9nom\u00e8ne est appel\u00e9 diffusion de Rayleigh ou diffusion \u00e9lastique.   Une petite partie de la lumi\u00e8re diffus\u00e9e pr\u00e9sente un d\u00e9calage d\u2019\u00e9nergie par rapport \u00e0 la fr\u00e9quence du laser en raison des interactions entre les ondes \u00e9lectromagn\u00e9tiques incidentes et les niveaux d\u2019\u00e9nergie vibrationnelle des mol\u00e9cules de l\u2019\u00e9chantillon. En repr\u00e9sentant graphiquement l\u2019intensit\u00e9 de la lumi\u00e8re d\u00e9cal\u00e9e en fonction de la fr\u00e9quence, on obtient un spectre Raman de l\u2019\u00e9chantillon.   Les spectres Raman sont g\u00e9n\u00e9ralement repr\u00e9sent\u00e9s en fonction de la fr\u00e9quence du laser, ce qui signifie que la bande de Rayleigh se situe entre 0<sup> cm\u207b\u00b9<\/sup>. Sur cette \u00e9chelle, les positions des bandes correspondent aux fr\u00e9quences associ\u00e9es aux niveaux d\u2019\u00e9nergie des vibrations des diff\u00e9rents groupes fonctionnels.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-what-does-raman-spectroscopy-provide-information-about\"><strong>Quelles informations la spectroscopie Raman fournit-elle ?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La spectroscopie Raman fournit des informations sur la structure chimique et l\u2019identit\u00e9 d\u2019un mat\u00e9riau, ainsi que sur sa phase et son polymorphisme, ses contraintes\/d\u00e9formations intrins\u00e8ques, sa contamination et ses impuret\u00e9s. La spectroscopie Raman trouve \u00e9galement des applications tant qualitatives que quantitatives. Les spectres permettent une identification sp\u00e9cifique et chimique gr\u00e2ce \u00e0 des algorithmes de recherche effectu\u00e9s sur des bases de donn\u00e9es num\u00e9riques. Les largeurs de bande sont proportionnelles \u00e0 la concentration, ce qui signifie que la spectroscopie Raman se pr\u00eate \u00e0 une analyse quantitative simple.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-benefits-of-raman-spectroscopy\"><strong>Avantages de la spectroscopie Raman<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les spectres Raman pr\u00e9sentent g\u00e9n\u00e9ralement une \u00ab empreinte chimique \u00bb distincte pour une mol\u00e9cule ou un mat\u00e9riau sp\u00e9cifique, ce qui permet d\u2019identifier rapidement le mat\u00e9riau ou de le distinguer d\u2019autres. Outre les syst\u00e8mes Raman de cartographie (ou d\u2019imagerie), la cr\u00e9ation d\u2019images repose sur le spectre Raman de l\u2019\u00e9chantillon. Ces <a href=\"https:\/\/synrad.wistia.com\/medias\/wkhpeih1jd?embedType=iframe&#038;videoWidth=1200\" target=\"_blank\" rel=\"noreferrer noopener\">images<\/a> montrent la r\u00e9partition des composants chimiques individuels, des polymorphes et des phases, ainsi que les variations de cristallinit\u00e9.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-uses-of-raman-spectroscopy\"><strong>Applications de la spectroscopie Raman<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La spectroscopie Raman est souvent utilis\u00e9e en analyse microscopique, avec une r\u00e9solution spatiale de l\u2019ordre de 0,5 \u00e0 1 \u00b5m gr\u00e2ce \u00e0 un microscope Raman. Le microscope Raman associe un spectrom\u00e8tre Raman \u00e0 un microscope standard. Il permet une visualisation \u00e0 fort grossissement d\u2019un \u00e9chantillon et une analyse Raman \u00e0 l\u2019aide d\u2019un spot laser microscopique.   La spectroscopie Raman est \u00e9galement utile pour l\u2019analyse de particules de taille microm\u00e9trique en suspension. Elle peut aussi servir \u00e0 analyser des couches individuelles au sein d\u2019un \u00e9chantillon multicouche. Elle permet alors de localiser avec pr\u00e9cision les contaminants et les caract\u00e9ristiques situ\u00e9s sous la surface d\u2019un \u00e9chantillon transparent.   La spectroscopie Raman est fr\u00e9quemment utilis\u00e9e pour l&rsquo;analyse de solides, de poudres, de liquides, de gels, de mat\u00e9riaux inorganiques, organiques et biologiques, de produits chimiques purs, de m\u00e9langes et de solutions.  Elle est en outre utilis\u00e9e pour les oxydes m\u00e9talliques et leurs processus de corrosion.   La spectroscopie Raman est souvent utilis\u00e9e dans les domaines de l\u2019art et de l\u2019arch\u00e9ologie pour caract\u00e9riser les pigments, les c\u00e9ramiques et les pierres pr\u00e9cieuses. Elle est \u00e9galement employ\u00e9e en g\u00e9ologie pour identifier les min\u00e9raux et leur r\u00e9partition, les inclusions fluides et les transitions de phase. De plus, la spectroscopie Raman est utile pour le diagnostic de maladies, pour garantir l\u2019uniformit\u00e9 et la r\u00e9partition des composants dans les produits pharmaceutiques, ainsi que pour surveiller les r\u00e9actions chimiques.   De nombreux <a href=\"https:\/\/novantaphotonics.com\/industry-category\/laser-reseach-raman-spectroscopy\/\">lasers<\/a> de Laser Quantum sont adapt\u00e9s \u00e0 la spectroscopie Raman.
