burns_1986 ========== R\. C\. Burns, C\. Graham and A\. R\. M\. Weller, "Direct measurement and calculation of the second refractivity virial coefficients of gases", Mol\. Phys\. 59, 41 \(1986\) `Source record `__ · :doc:`Catalogue ` · :doc:`Review register ` DOI: `10\.1080/00268978600101901 `__ **Source kind:** measurement **Recorded technique:** The differential decompression method of Buckingham, Cole and Sutter on the apparatus of Buckingham and Graham \(1974\), moved to Natal\: a vibration\-compensated interferometer \(stability better than 1e\-3 fringe\) compares a reference beam with a beam through two matched cells A and B; the phase change when gas in A expands into the evacuated B gives B\_n \(Eq\. 2\.3\), and two successive decompressions cancel the cell mismatch\. A\_n from separate absolute refractive\-index measurements, several hundred fringes counted, phases to better than 1e\-2 fringe, MKS Baratron pressures \(\+\-0\.05 %\), water\-jacket temperature to \+\-0\.05 K, densities from Dymond and Smith's second virial coefficients\. He\-Ne 632\.8 nm and argon\-ion 514\.5, 488\.0 and 457\.9 nm \(pp\. 42\-46\)\. **Materials in structured entries:** Ar, CH4, CO2, He, Kr, N2, Ne, SF6, Xe **Dataset quantities:** molar\_refractivity, refractivity\_virial\_coefficient **Contents:** 44 datasets; 0 formulas. Curation notes -------------- Page numbers are the journal's \(41\-64\); pdf page 1 is a cover, so p\. = pdf page \+ 39\. Definitions \(p\. 41, Eq\. 1\.1\)\: R\_m = \(n^2 \- 1\)/\(\(n^2 \+ 2\) rho\) = A\_R \+ B\_R rho \+ \.\.\., rho in mol per volume, so A\_R is the package's molar refractivity and B\_R its refractivity\_virial\_coefficient; A\_R = 2 A\_n/3 and B\_R = 2 B\_n/3 \- A\_n^2/9 \(Eqs\. 2\.4\-2\.5\)\. Units\: Table 2 prints 10^6 A\_R/m^3 mol^\-1 \(= cm^3/mol\) and Table 3 10^12 B\_R/m^6 mol^\-2 \(= cm^6/mol^2\)\. Temperature\: not stated with Tables 2 and 3; Tables 6 and 12 compare the 632\.8 nm observed values 'at room temperature \(298\.2 K\)' \(pp\. 58, 63\), which the B\_R datasets take \(achtermann\_1991 lists them at 298 K\)\. Wavelengths\: the laser lines' conventional labels, 632\.8 nm \(He\-Ne\) and 514\.5, 488\.0, 457\.9 nm \(Ar\+\), which are air wavelengths \(the He\-Ne line is 632\.99 nm in vacuum; quoted from memory, not from a library source\)\: standard\_air\. The difference changes A\_R by about 1e\-5 of itself\. Uncertainties \(p\. 46\)\: A\_R, 'For each gas at least three separate measurements were made at each wavelength\. In all cases the standard deviation was less than 0\.1 per cent' \(taken as one sigma; pressure \+\-0\.05 %\)\. B\_R \(p\. 46\)\: 'the quoted uncertainties are obtained by taking the sum of three uncertainties, namely the standard deviation, the variation in B\_R due to a \+\-30 per cent error in the calculated correction for the effects of cell distortion due to gas pressure, and an uncertainty due to drift in the end\-point after a decompression\. In most cases the standard deviation accounts for roughly half the quoted uncertainty\.' The per\-point column is that sum \(level not a standard one\: 'not stated'\)\. The authors report 'evidence of a possible wavelength dependence of B\_R' \(abstract, pp\. 46\-47\) beyond the dispersion of alpha, which theory does not predict; B\_R of Xe falls from 25\.5 at 632\.8 nm to 14\.9 at 488\.0 nm\.
