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

Nonresonant \('electronic'\) third\-order susceptibilities of gases from CARS at 532 \+ 683 nm \(omega\_1 \- omega\_2 = 4155 cm^\-1\), with a compilation of other FWM, dcSHG, Kerr and THG values \(Table I\) and of hydrocarbons and halocarbons \(Table II, of which only CH4 is curated and repeats Table I\)\. NO, CS2, H2O, H2S, NH3 and SiF4 are not curated species \(skipped\)\.

Definition \(p\. 6301\)\: 'Our definition of chi is based on the convention of Ward and co\-workers', Eq\. \(1\)\: P\(w3\) = K chi\(\-w3; w1, w1, \-w2\) E1^2 E2\*, K = 3/4 for CARS, 1/4 for THG, 3/2 for dcSHG, 3 for the Kerr effect, so that all 'approach the same static limit'\: chi = gamma\_T/6 per molecule, in cm^6/\(erg molecule\) \(= esu per molecule; 'to convert to a volume susceptibility multiply by molecules/cm^3\. To convert to SI units of C^4 m^4/J^3 multiply by 10^9/c^4 \(c in m/s\)', Table I note a\)\. The compiled dcSHG, Kerr and THG values are in the same convention \(identical to ward\_1969, ward\_1979 and Buckingham and Dunmur's gamma/6\)\.

Reference standard \(pp\. 6301\-6303\)\: the resonant susceptibility of the H2 Q1 line, Eq\. \(2\) chi\_r = alpha\_par^2 / 3 hbar \(delta \- i gamma\) \[printed '3 h'\], Eq\. \(3\) alpha\_par^2 = \(c/w2\)^4 \(d sigma/d Omega\)/\(1 \+ rho\_l\), with Schrotter's N2 Q\-branch standard \(schrotter\_1979\: 5\.05e\-48 cm^6/sr / \(2 pi\)^4 = 3\.240e\-51\) alpha^2 = \(3\.24 \+\- 0\.06\) x 10^\-51 cm^6/sr \(Eq\. \(4\)\), H2/N2 ratio S\_j = mean of 3\.45 and 3\.64 \(515, 488 nm\) with 10 % uncertainty, Q1 fraction 0\.664 at 20 C, rho\_l = 0\.036\: alpha\_par^2 = \(7\.36 \+\- 0\.75\) x 10^\-51 cm^6/sr; Owyoung's linewidth Delta nu = A/rho \+ B rho \(A = 301\.6 \+\- 8\.7 MHz amagat, B = 51\.3 \+\- 0\.6 MHz/amagat\)\: at 7000 Torr, 20 C \(8\.53 amagat\) 473\.1 \+\- 6\.1 MHz and \|chi\_r0\| = \(1\.57 \+\- 0\.16\) x 10^\-33 cm^6/\(erg molecule\); for Rado's 17\.0 atm \(15\.68 amagat\) 823\.8 MHz and \(0\.899 \+\- 0\.093\) x 10^\-33\. Measured chi\_nr\(N2\)/chi\_r0\(H2\) = \(6\.88 \+\- 0\.46\) x 10^\-5 \(seven sets of 1000 shots\), and \(6\.26 \+\- 0\.6\) x 10^\-5 from Rado's data scaled by the linewidths; their average gives chi\(N2\) = \(102\.9 \+\- 14\) x 10^\-39 at omega\_1 \- omega\_2 = 4155 cm^\-1 \(p\. 6303\)\. Subtracting the calculated N2 vibrational Q\-branch \(\-2\.9\) and rotational \(\+0\.8\) contributions gives the electronic \(105 \+\- 14\) x 10^\-39, the reference of the whole FWM column c and, through N2, of columns d and e\. Every FWM value is therefore scaled to a Raman\-cross\-section standard, uncertain by about 13 %; field\-induced\-absorption values of alpha\_par^2 \(7\.8 to 11\.7, mean 9\.6 x 10^\-51\) would raise all FWM entries by 30 % \(p\. 6305; 'the relative FWM values compiled here are easily rescaled'\)\. \(Shelton and Rice 1994 rescale Lundeen's values\.\)

Part \(Table I note b\)\: the rotational and vibrational Raman contributions at the experiment's omega\_1 \- omega\_2 \(columns 1\-2, calculated from Raman and polarizability data\) 'have been subtracted from the measured FWM values to obtain the electronic susceptibilities listed' \(all FWM columns, and Table II\)\: the FWM values are recorded electronic, the columns 1\-2 as vibrational and rotational \(use check\)\. Nanosecond pulses; the subtraction is of the Raman\-resonant terms at 4155 cm^\-1 detuning, the 'subtraction of computed gamma^vR'\. Doubt\: the text gives N2's rotational contribution as 0\.8 x 10^\-39 but Table I prints 3 \(image checked\)\.

Uncertainties\: column c 'relative uncertainties estimated at less than 5 % \(15 % for He\)' \(note c\), plus the 13 % of the N2 scale; helium in the text \(p\. 6304\) 3\.2 \+\- 0\.7 \('reflects that for chi\_nr of N2 and also that of the chi\_nr\(He\)/chi\_nr\(N2\) measurement'\)\. Rado's column\: 'reproducibility of 10 % is cited' \(note d\); Hauchecorne et al\.\: 'original data given to only one or two significant figures' \(note e\)\. dcSHG and THG \+\-\: relative \(notes f, h\); Kerr \+\-\: absolute \(note g\)\.

The paper expects chi\_Kerr \< chi\_dcSHG ~ chi\_FWM\(694\) \<~ chi\_FWM\(532\) \< chi\_THG for Ar and Kr \(p\. 6304\), doubts Buckingham et al\.'s CO2 Kerr value and Rado's D2 \(H2 impurity\), and estimates He's FWM theory at about the dcSHG value 3\.8 \(DeMartini et al\.'s FWM He is about seven times it\)\.
