**Source kind:** measurement

**Recorded technique:** Two coupled grating interferometers at the vacuum wavelength 632\.99 nm \(He\-Ne\)\: interferometer I \(two matched cells in series, with compensation chambers\) counts the fringe change Delta K during an isothermal overflow expansion into an evacuated twin cell, which measures the departure of n \- 1 from proportionality to density \(Eqs\. 7\-12\); interferometer II \(cells in parallel\) gives the absolute fringe count K and controls the expansion; expansions in both directions cancel cell mismatch \(Eq\. 8\)\. Pressures to 35 MPa \(to twice the critical density\); cell and compensation\-chamber distortion corrected \(Eqs\. 17\-19\)\. A\_R from separate absolute n\(P, T\) isotherms, the pressure from the refractive index of nitrogen calibrated against a piston gauge, extrapolated to zero density with the virial equation of state \(Eqs\. 13\-16\)\. CO2, H2, N2, He, Ar and CH4 at 323\.15 K; CH4, C2H4, C2H6, SF6 at 373\.15 K \(pp\. 5669\-5675\)\.

**Materials in structured entries:** Ar, CH4, CO2, H2, He, N2, SF6

**Dataset quantities:** molar\_refractivity, refractivity\_virial\_coefficient

**Contents:** 109 datasets; 0 formulas.

Definitions \(p\. 5669\)\: R\_m = \(n^2 \- 1\)/\(\(n^2 \+ 2\) rho\) = A\_R \+ B\_R rho \+ C\_R rho^2 \+ D\_R rho^3 \(Eq\. 1\), rho molar density\: A\_R is the package's molar refractivity and B\_R its refractivity\_virial\_coefficient\. The measured function is \(n \- 1\)/rho = A\_n \+ B\_n rho \+ \.\.\. \(Eq\. 2\) with A\_R = 2 A\_n/3, B\_R = 2 B\_n/3 \- A\_n^2/9, C\_R = 2 C\_n/3 \- 2 A\_n B\_n/9 \- 4 A\_n^3/27 \(Eqs\. 3\-5\)\. Accuracy \(p\. 5670\)\: 'A rough estimate of the accuracy of the measured first refractivity virial coefficient is A\_R, \+\-0\.02 % and the accuracy of the higher\-order coefficients, except for H2 and He, is B\_R, \+\-2\-5 %; C\_R, \+\-3\-5 %; and D\_R, \+\-30\-50 %'\. The B\_R, C\_R, D\_R uncertainties of Table II are 'three standard deviations from the least\-squares fit as well as errors due to cell distortion and adsorption' \(p\. 5675\); the level of the A\_R uncertainties and of the literature values is not stated\. R = 8\.314471 J/\(K mol\)\. Gas purities \(Table I\)\: CH4 99\.9995 %, CO2 99\.995 %, SF6 99\.998 %, H2 99\.999 %, N2 99\.9995 %, He 99\.996 % \(Linde; O2 \< 5, N2 \< 20, H2O \< 5, Ne \< 10 ppm\), Ar 99\.998 %\.

Wavelengths \(Table II caption\)\: the refractivity virial coefficients are at the vacuum wavelength 632\.99 nm 'except for the values of CH4 from Olson \(Ref\. 9\), \(lambda = 546\.2 nm\), C2H6 from Sliwinski \(Ref\. 10\), \(lambda = 589\.3 nm\), H2 from Diller \(Ref\. 8\), \(lambda = 546\.2 nm\), the theoretical value for H2 from Orcutt and Cole \(Ref\. 36\), \(lambda infinite\), and the values of He from Orcutt and Cole \(Ref\. 36\) and Kirouac and Bose \(Ref\. 55\), \(lambda infinite\)'\. The classical \(dipole\-induced\-dipole\) theoretical B\_R rows carry no wavelength and are stored at 632\.99 nm; Dacre's helium B\_eps \(Ref\. 59\) is static and stored at infinity\. 'Calculated values of A\_R have been computed from Landolt\-Boernstein Tables \(Ref\. 23\)' \(caption\)\: the A\_R of the Theory rows\. Temperatures printed '\.\.\.' are stored with the row id 'unknown' and no temperature parameter\.

Extracted \(OEP 4, the quantity's order 3 and 4\), Table II, cm^9/mol^3 and cm^12/mol^4\: CH4 C\_R \-324 \+\- 5 \(323 K, this work\), \-317 \+\- 10 \(373 K, this work\), \-326 \+\- 10 \(Achtermann et al\. 1986\), \-345 \+\- 15 \(Montixi and Coulon\), \-320 \(Olson\); CO2 \-287 \+\- 8 \(this work\), \-224 \+\- 40 \(Jaeschke\); SF6 C\_R \-2783 \+\- 130 and D\_R 37 800 \+\- 8000 \(373 K, this work\); H2 \-13\.7 \+\- 2\.0 \(this work\); N2 \-99\.8 \+\- 2\.8 \(this work\), \-107 \+\- 5 \(Achtermann et al\. 1986\), \-85 \+\- 10 \(Montixi et al\.\); He\: Kirouac and Bose's C\_eps \-0\.84 \+\- 1\.20, and this work's bound \-1\.0 \< C\_R \< 0\.4 \(p\. 5680, from the fringe\-count error\); Ar \-86\.6 \+\- 2\.0 \(this work\), \-79 \+\- 10 \(Coulon et al\.\)\. Ethylene and ethane \(C2H4 C\_R \-1591 \+\- 84, D\_R 5540 \+\- 2100; C2H6 C\_R \-2227 \+\- 75, D\_R 12 400 \+\- 3500, at 373 K\) are not species\. Table III's B\_OR = B\_eps \- B\_R, B\_FIR and B\_IR \(collision\-induced absorption\) are not refractive quantities; its B\_R column repeats this work's values \(and 'estimated' ones, note c\) except CH4 at 323\.15 K, printed 6\.11 \+\- 0\.10 against Table II's 6\.08 \+\- 0\.10 \(unresolved; Table II is extracted\)\.

Helium \(pp\. 5675\-5676, 5680\-5682\)\: Delta K for He at 323\.15 K \(15\.3\-35\.7 MPa, ten repetitions at 35\.7 MPa\: \-0\.58 \+\- 0\.10 fringes against K = 1351, distortion correction 0\.56\) is 'practically zero', so B\_n = C\_n = 0 and B\_R = \-0\.068 comes only from \-A\_n^2/9; without the distortion correction it would be \-0\.1\. 'To the best of our knowledge, B\_R of He has never been measured before\.' Puchalski et al\. \(2016\) find this work's helium A\_R 'ten times larger than their uncertainty' off the ab initio value \(the measured A\_R is A\_eps \+ A\_mu at 323 K\)\. Olson's reference is printed 'J\. D\. Olsen' in the reference list\.
