This work builds on previous studies aimed at exploring the coupling between neutral H2CC and HCCH isomers. One-photon photodetachment (PD) spectra with improved cooling and signal levels probe very weak transitions to vibrational levels of H2CC in which the \u03bd6 rocking mode is excited; this is the vibrational mode most strongly coupled to isomerization. In addition, vibrationally resonant two-photon detachment (VR2PD) experiments are carried out that probe PD from vibrationally excited anion levels to the same neutral \u03bd6 states and other low-lying vibrational levels of neutral vinylidene. The experimental spectra show a clear boundary in spectral complexity near the predicted barrier height for H2CC\u2192HCCH isomerization, indicating that vinylidene and acetylene states above the barrier are strongly mixed whereas states below the barrier are largely localized in their respective wells. This mixing is, however, largely absent in the cryo-SEVI spectra of D2CC\u2013. Comparison with quantum dynamics calculations based on an accurate full dimensional potential energy surface provides insight into the connection between the H2CC\u2013HCCH isomerization reaction and the vibrational structure of vinylidene, revealing pathways of intramolecular vibrational energy flow in the quantum state space of this prototypical system.<\/jats:p>","DOI":"10.1021\/jacs.6c07569","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T20:01:27Z","timestamp":1787256087000},"page":"36706-36715","source":"Crossref","is-referenced-by-count":0,"title":["Probing the Quantum\nNature of Intramolecular Vibrational\nEnergy Redistribution in HCCH\u2013H2CC Isomerization\nUsing High-Resolution Photoelectron Spectroscopy"],"prefix":"10.1021","volume":"148","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1559-2112","authenticated-orcid":true,"given":"Martin","family":"DeWitt","sequence":"first","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8567-1051","authenticated-orcid":true,"given":"Dongzheng","family":"Yang","sequence":"additional","affiliation":[{"name":"University of New Mexico , , , ,","place":["Albuquerque, New Mexico, United States, 87131"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0068-373X","authenticated-orcid":true,"given":"Jascha A.","family":"Lau","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Korina","family":"Vlahos","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9901-053X","authenticated-orcid":true,"given":"Hua","family":"Guo","sequence":"additional","affiliation":[{"name":"University of New Mexico , , , ,","place":["Albuquerque, New Mexico, United States, 87131"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3762-9473","authenticated-orcid":true,"given":"Daniel M.","family":"Neumark","sequence":"additional","affiliation":[{"name":"University of California , , , ,","place":["Berkeley, California, United States, 94720"]},{"name":"Lawrence Berkeley National Laboratory , , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"2026090312095604300_cit1","volume-title":"Unimolecular Reactions","author":"Robinson","year":"1972"},{"key":"2026090312095604300_cit2","doi-asserted-by":"publisher","first-page":"241","DOI":"10.1146\/annurev.pc.45.100194.001325","article-title":"Intramolecular Dynamics from Eigenstate-Resolved\nInfrared Spectra","volume":"45","author":"Lehmann","year":"1994","journal-title":"Annu.
