In this method, the absorption spectrum of the material is obtained as a function of applied potential, and the results are used to understand its electrochemical behavior. The standard approach uses chronoamperometry, in which a constant potential is applied, and an absorption spectrum is measured at electrochemical equilibrium for a series of potentials selected across the electrochemical window of the sample. However, this method is limited by slow, labor-intensive data acquisition and lack of time-resolved absorbance information. Herein, we describe an automated absorbance spectroelectrochemical method that couples a high-speed, broadband optical absorbance instrument with normal pulse voltammetry to capture full absorbance spectroelectrochemistry spectra in a single measurement. The instrument measures absorption spectra over a 400\u20132500\u2005nm window at a maximum spectral acquisition rate of 200\u2005Hz (5\u2005ms response time). We demonstrated the capability of this spectroscopy technique to automatically obtain a full set of potential-dependent absorbance spectra and absorbance transients by applying it to study the electrochemical charging behavior of a polythiophene electrode, which was time-resolved at 1 spectrum\/s.\n                  <\/jats:p>","DOI":"10.1177\/00037028261479001","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T18:59:06Z","timestamp":1786042746000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Automating Absorbance Spectroelectrochemistry Using Normal Pulse Voltammetry"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9332-2536","authenticated-orcid":false,"given":"Caitlyn","family":"Clark","sequence":"first","affiliation":[{"name":"Auburn University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3741-7702","authenticated-orcid":false,"given":"Christopher","family":"Grieco","sequence":"additional","affiliation":[{"name":"Auburn University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/elan.201900075"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1039\/C7NR07803J"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/aelm.202300082"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-018-05235-z"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/acspolymersau.2c00066"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41563-019-0435-z"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202300308"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1039\/D3TC03058J"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1039\/D5SC04619J"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemrev.1c00597"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/pol.20210503"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.adi3536"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpcc.0c09527"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemmater.3c02122"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0728(91)85273-R"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar00027a001"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1117\/12.3063286"},{"key":"e_1_3_3_19_2","volume-title":"Electrochemical Methods: Fundamentals and Applications, Third Edition. third","author":"Bard JA","year":"2022","unstructured":"Bard JA, Faulkner RL, White SH.
