Qualitative agreement between the calculated polarisations and the measured ones shows that noticeable variation of the observed polarisation with increasing impact energy is ascribed to rotation of the molecular axis following the change of scatter ing angle. The contribution of the secondary processes and the influence of the deviation of the symmetry axis of the atom from the internulear axis of the separating particles, to the polarisations were discussed.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127531436","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}

Although a diffuse reflection method has been widely used for analyzing highly scattering samples, some problems have been pointed out for example, this method does not enable us to obtain sharp absorption peaks. The problem of the background disturbing the accuracy of an analysis has also remained unsolved. In this paper, pitches are measured as typical highly scattering samples by FT-IR spectrometer. Then, new dilution materials are developed and proposed in order to obtain fine spectra. As a result, the spectra measured by using our new dilution materials have remarkably fine quality. Our method may be able to assist in solving the existence of backgrounds, those which have remarkably disturbed the accuracy in analyzing spectra.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126947933","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}

Its capability of chromatographic separation of atomic vapor from non-atomic species was examined on the direct atomization of biological samples. The SCA was heated up to 1420°C. The species formed by decomposition under a flow of argon were followed by reaction and/or separation in the SCA packed with graphite granules, and subsequently the atomic absorption of Cd was measured at the column outlet. The non-atomic absorption gave no background absorption problems because of the gas chromatographic separation between non-atomic and atomic vapors through the SCA.","PeriodicalId":199016,"journal":{"name":"Journal of the Spectroscopical Society of Japan","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126821620","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 main cause for the small slope of the calibra tion curve has been referred to self-absorption of the spectral line. Efforts have therefore been made to reduce the effect of self-absorp tion by selecting the proper analytical condi tion 1). In this paper, a calculation procedure for correcting self-absorption is proposed and improvement of the slope of the calibration curve is reported. The experiment was carried out using a normal laser microprobe with auxiliary spark excitation. Figure 1 shows the arrangement of spark electrodes and the sample.
