With this cell, the absorbance of solution is amplified several times higher than that expected from the cell length, and the observed calibration curve provides a strong curvature. Such characteristics of LCC are ascribable to the multi-reflection of source light inside the cell. Reflection petterns of source light in side LCC have been, therefore, discussed in relation to the enhancement of the absorption and anlytical calibration curves.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124632243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The α2-helix is considered to be as the most labile structure in SSI. The complete transformation of local structure around aromatic residues at pH 2 were detected by difference absorption, CD and fourth-derivative absorption spectra in the near-UV range.

Three coupling methods, i. e. rigid coupling, coupling using liquids, and coupling using sheet materials, were tested in terms of signal intensity and image distortion. Highly viscous liquid proved to be nearly as good as the rigid combination in terms of signal intensity and distortion over the frequency range 200 Hz to 200 kHz. Taking separability into consideration, the use of viscous liquid under pressure is the most practical coupling method.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"5 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114039573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
