<dcterms:abstract xml:lang="fr">Cette thèse explore les effets du Couplage Fort Vibrationnel (VSC) sur la polarité des solvants, les forces de dispersion de London et l’auto-diffusion de l’eau. L’étude utilisant le colorant solvatochromique de Reichardt suggérait une diminution de la polarité des solvants sous VSC. Cependant, des analyses ultérieures ont révélé que les artefacts optiques, dus à un traitement incorrect des spectres UV/vis et à la réflectivité, étaient responsables des observations, ce qui a conduit à la rétractation de l’article publié. Cette expérience a inspiré l’étude des forces de dispersion de London. Grâce à des balances moléculaires et des cavités Fabry-Perot adaptées à la RMN, j’ai démontré que le VSC modifie les équilibres conformationnels, confirmant ainsi des prédictions théoriques. Enfin, l’étude de l’auto-diffusion de l’eau a montré que ces cavités ne sont pas compatibles avec la RMN DOSY et que des simulations de Matrice de Transfert sont essentielles pour interpréter correctement les spectres IR et calculer l'énergie de Rabi des bandes d’absorption larges comme l’étirement OH de l’eau.</dcterms:abstract>
<dcterms:abstract xml:lang="en">This thesis explored the effects of Vibrational Strong Coupling (VSC) on solvent polarity, London dispersion forces, and water self-diffusion. The study using the solvatochromic Reichardt’s dye suggested a decrease in solvent polarity under VSC. However, further analysis revealed that optical artifacts due to incorrect handling of UV/vis spectra were responsible for these observations, leading to the retraction of the published article. The next study focused on the influence of VSC on London dispersion forces. Using dispersion-sensitive molecular balances and leveraging fixed-width Fabry-Perot cavities compatible with NMR spectroscopy I showed that VSC modulates dispersion-driven conformational equilibria providing direct experimental proof for the modification of this type of supramolecular interaction confirming previous indirect reports and theoretical predictions. Finally, the study of water diffusion showed that FP cavities are not compatible with DOSY NMR and that Transfer Matrix simulations are essential to correctly interpret IR spectra and calculate the Rabi energy of broad absorption bands like the OH stretching mode of water.</dcterms:abstract>
