We have used spectra from hollow-cathode lamps that have been recorded with the Fourier Transform Spectrometer at Kitt Peak National Observatory. Measurements of isotope shifts yield useful information about atomic and nuclear properties. With high-resolution spectroscopy at modern telescopes it is also possible to observe isotope shifts in stellar spectra (Leckrone et al. 1991). The importance of a general knowledge about isotope structure for studies of the solar spectrum has recently been pointed out (Kurucz 1992). This is especially true for elements having line-rich spectra and a high solar abundance. Ignoring isotope structure when constructing synthetic spectra may introduce systematic errors in the calculation of line profiles and may therefore affect e.g. abundance determinations.","PeriodicalId":159025,"journal":{"name":"High Resolution Fourier Transform Spectroscopy","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124806289","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}

This simple diatomic molecule was previously known only from matrix isolation ESR studies by Knight et al. [1] and the theoretical calculations of Bauschlicher et al.

A search was made for this system of AlC in emission from a hollow cathode source using the 1m Fourier transform spectrometer at Kitt Peak National Observatory. The initial search was partially successful in that two weak bands were observed that had the correct form and could not be attributed to any known impurity spectrum. The experiment was repeated using more sensitive detectors and a narrower detection bandwidth, resulting in the spectra described here.","PeriodicalId":159025,"journal":{"name":"High Resolution Fourier Transform Spectroscopy","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115114507","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}

Species concentrations are determined by ratioing measured spectral line intensities to those for known \"standard\" solutions, and/or by adding quantitative \"spikes\" to the sample. Under normal operating conditions, the viewing zone utilized for chemical analysis is near local thermodynamic equilibrium (LTE), with an excitation temperature of about 6300K and an electron density of about 1016 cm-3. The high excitation energy is a mixed blessing, providing high sensitivity for about 70 elements, along with the possibility of spectral interferences from concomitant species. Reasonably high optical dispersion is employed to minimize spectral interferences, and interferences are normally characterized by line profiling and spectral tables.","PeriodicalId":159025,"journal":{"name":"High Resolution Fourier Transform Spectroscopy","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114296418","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}
