gurtler_1977 ============ P\. Gürtler, V\. Saile and E\. E\. Koch, "High resolution absorption spectrum of nitrogen in the vacuum ultraviolet", Chem\. Phys\. Lett\. 48, 245 \(1977\) `Source record `__ · :doc:`Catalogue ` · :doc:`Review register ` DOI: `10\.1016/0009\-2614\(77\)80308\-4 `__ **Source kind:** measurement **Recorded technique:** Absolute photoabsorption of N2 with synchrotron radiation from the DORIS storage ring \(DESY\) and a 3 m normal\-incidence monochromator, resolution 0\.03 A, photoelectric recording \(sodium salicylate and an EMI 9804 photomultiplier\); a windowless cell of 60 cm at 1e\-4 to 1e\-1 torr \(membrane manometer\); N2 99\.997 % \(pp\. 245\-247\)\. **Materials in structured entries:** None recorded. **Dataset quantities:** None recorded. **Contents:** 0 datasets; 0 formulas. Curation notes -------------- Journal pages 245\-250 = PDF pages 1\-6\. N2 only\. No datasets\: the absolute absorption cross section is given only in figures \(Fig\. 1\: 990\-660 A; Fig\. 2\: 700\-450 A, with a Fano\-profile inset\), and the band oscillator strengths f\(v'\) of the b 1Pi\_u and b' 1Sigma\_u^\+ progressions only in Fig\. 3 \(plotted with the vibrational spacings DeltaG\(v'\)\)\. The abstract says 10\-35 eV; the figures cover 12\-30 eV \(1000\-400 A\)\. No table; the text gives no cross\-section values and states no uncertainty\. What the text states \(pp\. 247\-249\)\: agreement of the absolute cross section with Carter \(1972\), Huffman et al\. and Lee et al\. \(1973\) \('good agreement'\); four regions \(discrete bands with rotational structure above 795\.9 A; sharp Rydberg bands 795\-730 A on a continuum; below 730 A autoionisation 'apparent emission' structure; a vibrational progression near 500 A\); Rydberg series to n = 23; quantum defects 1\.05 and 0\.17 \(series to A 2Pi\_u\), 0\.15 \(nd sigma\_g\) and 0\.94 \(ns sigma\_g\) \(to B 2Sigma\_u^\+\), about 0\.9 near 500 A \(to the C 2Sigma\_u^\+ state\); the 5d sigma resonance halfwidth 20 meV \(autoionisation rate 3e13 s^\-1\), 6s sigma 2e13 s^\-1\. None is a dispersion quantity\. The data would need the tabulated cross section \(the authors' or a later compilation, not in the library\)\. **Recorded bibliographic identity status:** VALIDATED\_WITH\_WARNINGS. This concerns identification of the source; it does not establish the scientific correctness of its contents. Datasets -------- No datasets are recorded. Formulas -------- No formulas are recorded. Corrections ----------- No dataset errata are recorded in this source record. Formula corrections, where recorded, appear with their formulas above. Curation notes may also discuss corrections or unresolved interpretation. Consult the :doc:`review register ` for the checks and decisions.
