**Source kind:** measurement

**Recorded technique:** Nonlinear interferometry of CARS\: two gas cells in series \(argon reference, sample\), with a phase\-shifting unit of sliding BK\-7 wedges between them; the fringe amplitude of the summed CARS signal against the sample pressure \(up to 2 bar, transducer calibrated to 0\.1 %\) gives the sample's nonresonant susceptibility relative to argon's\. BOXCARS phase matching, injection\-seeded single\-mode Nd\:YAG pump at 532 nm \(\< 100 MHz, 7\-8 ns\) and a single\-mode pulsed dye Stokes \(about 500 MHz\), Raman shift 2157 cm^\-1 \(2334 cm^\-1 for CO, CF4, H2\), parallel polarizations; shot\-by\-shot normalization to propane's nonresonant CARS\.

**Materials in structured entries:** Ar, CH4, CO, CO2, H2, N2, O2

**Dataset quantities:** hyperpolarizability\_ratio, nonlinear\_susceptibility

**Contents:** 53 datasets; 0 formulas.

Curation notes
--------------

Nonresonant CARS susceptibilities relative to argon, for C2H2, CO2, CH4, N2, O2, C3H8, CO, CF4 \('Freon'\) and H2; acetylene, propane and CF4 are not curated species \(skipped\)\.

Definitions\: the CARS susceptibility of the CARS literature, Eq\. \(14\), p\. 1025 \(after Druet and Taran\)\: chi\_CARS\(3\) = \(N/hbar\) sum \(rho\_aa \- rho\_bb\) c^4/\(w1 w2^3\) \(d sigma/d Omega\) / \(w\_ba \- w1 \+ w2 \+ i gamma\_ba\), N the number density; the off\-resonant Raman part, Eq\. \(15\), neglects i gamma\. Values per amagat, 10^\-18 cm^3/\(erg amagat\)\. The absolute scale is argon's 9\.46 x 10^\-18 cm^3/\(erg amagat\) 'reported by Rosasco and Hurst' \(Table 1 note b\)\: rosasco\_1985's 3 sigma/24 = 0\.788 x 10^\-18 esu times 12 \(their chi^CARS = 12 chi\_1111\), the same convention as farrow\_1985\: chi^CARS = N0 gamma\_T/2 at 1 amagat, gamma\_T = 2 chi^CARS/N0 \(1e\-18 per amagat = 147\.8 au\)\. Eqs\. \(1\)\-\(13\) \(pp\. 1022\-1023\) model the interference\: I ~ 1 \+ eta^2 \+ 2 eta cos\(\.\.\.\), eta = chi\_s P\_s phi / \(chi\_r P\_r\); the fringe amplitude is linear in the sample pressure\.

Results\: Table 1 \(p\. 1025\) ratio of fringe slopes to argon's \(uncertainty 'usually about 2\-3 % and \.\.\. no larger than 5 %', p\. 1025\) and effective chi\_NR \(ratio x 9\.46\); Table 2 \(p\. 1025\) the off\-resonant Raman terms computed from Eq\. \(15\) with Schrotter and Klockner's \(curated as schrotter\_1979\) and Martin's cross sections; Table 3 \(p\. 1026\) the electronic chi\_NR = effective minus off\-resonant \(checked\: CO2 10\.8 \+ 0\.35 \+ 0\.62 = 11\.77, CH4 26\.9 \- 4\.17 = 22\.73, N2 10\.2 \- 2\.30 = 7\.90, O2 7\.31 \+ 0\.67 = 7\.98, CO 10\.3 \+ 2\.03 = 12\.33, H2 6\.66 \- 0\.77 = 5\.89 against 5\.90 printed\)\. 'The uncertainties of the absolute values of the electronic susceptibility \.\.\. are estimated to be 10 %' \(Table 3 note a\); 'overall uncertainty \.\.\. is less than 5 %' \(abstract, conclusion; the relative measurement\)\. Check measurement \(p\. 1026\)\: O2 at 2334 cm^\-1, effective 7\.28 \+\- 0\.18, off\-resonant \-0\.53, electronic 7\.81 x 10^\-18, 2\.1 % from the 2157 cm^\-1 value\.

Part\: the effective values contain the off\-resonant vibrational Raman tails at the measurement's Raman shift \(recorded total\); the electronic values subtract the computed tails \(the subtraction of computed gamma^v; no orientational term enters CARS at these detunings\)\. The library text of this paper has glyph errors \(10^\-18 as '10218', cm^\-1 as 'cm21', minus signs as '2'\); every value was read against the table images\.
