While donor−acceptor Stenhouse adducts (DASAs) are widely understood in photochemistry, the thermal switching pathways on the ground-state potential energy surface have remained unknown. Rapid-scan infrared absorption spectroscopy provides transient spectroscopic fingerprints after light-induced steps, interpreted via kinetic modeling and quantum-chemical calculations. This combined experimental–theoretical strategy maps multidimensional ground-state transformations, enables predictive guidance along the energy surface, and confirms experimentally how DASAs can be steered.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":40,"@type":76,"position":81},"https://docshare.wps.com/document/research-report/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/taming-the-complexity-of-donor-acceptor-stenhouse-adducts-infrared-motion-pictures-of-the-complete-switching-pathway/155529/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/taming-the-complexity-of-donor-acceptor-stenhouse-adducts-infrared-motion-pictures-of-the-complete-switching-pathway/155529.png","ImageObject",300,407,{"name":92,"@type":93},"Melati","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-08","2026-08-28",true,{"@type":102,"interactionType":103,"userInteractionCount":39},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What problem does the study address about donor−acceptor Stenhouse adducts (DASAs)?","Question",{"text":112,"@type":113},"It focuses on identifying the thermal switching pathways on the ground-state potential energy surface, which were previously unknown despite a well-understood photochemistry.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How are thermal switching pathways investigated in this work?",{"text":117,"@type":113},"The study uses rapid-scan infrared absorption spectroscopy to capture transient reaction signatures after light-induced structures form.",{"name":119,"@type":110,"acceptedAnswer":120},"How are the experimental spectra converted into mechanistic understanding?",{"text":121,"@type":113},"Kinetic modeling and quantum chemical calculations interpret the spectroscopic data as structural transformations across the multidimensional potential energy surface.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},155529,1787914267,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":39,"category_name":40,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":39,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":52,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":143},962085570644,"https://ap-avatar.wpscdn.com/davatar_994ba38a5ba835b3df7d355c54d3ed8d","University of Groningen  \nTaming the Complexity of Donor-Acceptor Stenhouse Adducts  \nZulfikri, Habiburrahman; Koenis, Mark A.
