Numerous asynchronous cross-peaks ubiquitously appeared in the concentration-dependent Raman spectra of these organic solvent mixtures. The result clearly demonstrated a deviation from ideal solution behavior, reflecting the presence of specific molecular interactions causing a subtle nonlinear spectral intensity response of Raman bands to the concentration changes. Furthermore, the combination of 2D-COS and low frequency Raman spectroscopy was extended to poly[(R)-3-hydroxybutyrate- co-(R)-3-hydroxyhexanoate] (PHBHx) copolymer solutions in CHCl\n                    <jats:sub>3<\/jats:sub>\n                    -HFIP co-solvents. The results suggest the existence of hydrogen bonding interaction between the PHBHx and HFIP, which is consistent with the previous infrared spectroscopic study of PHBHx solutions.\n                  <\/jats:p>","DOI":"10.1177\/0003702819848501","type":"journal-article","created":{"date-parts":[[2019,4,22]],"date-time":"2019-04-22T11:11:21Z","timestamp":1555931481000},"page":"1012-1018","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Two-Dimensional Correlation Spectroscopy (2D-COS) Studies of Solution Mixtures in the Low Frequency Raman Region"],"prefix":"10.1177","volume":"73","author":[{"given":"Shuyu","family":"Xu","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, University of Delaware, Newark, DE, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Bruce Chase","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Delaware, Newark, DE, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John F.","family":"Rabolt","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Delaware, Newark, DE, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0081-4739","authenticated-orcid":false,"given":"Isao","family":"Noda","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of Delaware, Newark, DE, USA"},{"name":"Danimer Scientific, Bainbridge, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,5,20]]},"reference":[{"key":"bibr1-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1002\/jrs.1250190202"},{"key":"bibr2-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpca.7b07033"},{"key":"bibr3-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1021\/acs.oprd.6b00199"},{"key":"bibr4-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1021\/acs.molpharmaceut.7b00803"},{"key":"bibr5-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1366\/13-07329"},{"key":"bibr6-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1021\/ja00203a008"},{"key":"bibr7-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1366\/0003702904087398"},{"key":"bibr8-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1366\/0003702934067694"},{"key":"bibr9-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1366\/0003702934067513"},{"key":"bibr10-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1002\/0470012404"},{"key":"bibr11-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1063\/1.441449"},{"key":"bibr12-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1063\/1.451384"},{"key":"bibr13-0003702819848501","doi-asserted-by":"publisher","DOI":"10.1016\/0032-3861(81)90263-9"},{"key":"bibr14-0003702819848501","doi-asserted-by":"crossref","unstructured":"I.
