Yet, elucidating the fast fluctuation dynamics of freely diffusing single molecules in solution at room temperature, where a variety of chemical and biological processes occur, remains challenging. In this study, we report on fluorescence excitation correlation spectroscopy (FECS) of room-temperature solutions, which enables the study of spontaneous fluctuation of the excitation spectrum with microsecond time resolution. By employing Fourier transform spectroscopy with broadband femtosecond pulses and time-correlated single-photon counting, we achieved fluorescence excitation spectroscopy of a roomtemperature\nsolution at the single-molecule level. Building upon this single-molecule measurement, we obtained an excitation wavelength-resolved fluorescence autocorrelation function in the microsecond to millisecond range, demonstrating the potential of this method to elucidate fast, spontaneous, timedependent changes of excitation spectra in statistically equilibrium systems. With further development, this method will allow the study of spectral exchange associated with transitions between sub-ensembles of solution-phase molecules with unprecedented time resolution.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1021/acs.jpclett.4c01798","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2024 American Chemical Society","subitem_rights_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1948-7185","subitem_source_identifier_type":"EISSN"}]},"item_10001_text_23":{"attribute_name":"著者注記","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research Center of Integrative Molecular Systems (CIMoS), Institute for Molecular Science, National Institutes of Natural Sciences, 38 Nishigo-Naka, Myodaiji, Okazaki 444-8585, Japan"},{"subitem_text_language":"en","subitem_text_value":"Graduate Institute for Advanced Studies, SOKENDAI, 38 Nishigo-Naka, Myodaiji, Okazaki 444-8585, Japan"}]},"item_10001_text_28":{"attribute_name":"論文注記","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"This document is the Accepted Manuscript version of a Published Work that appeared in final form in [The Journal of Physical Chemistry Letters], copyright © [2024 American Chemical Society] after peer review and technical editing by the publisher.
