bridge_1964 =========== N\. J\. Bridge and A\. D\. Buckingham, "Polarization of Laser Light Scattered by Gases", J\. Chem\. Phys\. 40, 2733 \(1964\) `Source record `__ · :doc:`Catalogue ` · :doc:`Review register ` DOI: `10\.1063/1\.1725590 `__ **Source kind:** measurement **Recorded technique:** Depolarization of Rayleigh \(plus rotational Raman\) light scattered at 90 degrees from gases at 1 atm and 20 C inside the resonant cavity of a continuous He\-Ne laser \(6328 A, about 100 mW circulating\), Glan\-Thompson analyser, EMI 9558A photomultiplier with phase\-sensitive detection \(pp\. 2733\-2734\)\. **Materials in structured entries:** Ar, CO2, H2, N2, O2, SF6, Xe **Dataset quantities:** polarizability **Contents:** 7 datasets; 0 formulas. Curation notes -------------- A letter \(J\. Chem\. Phys\. 40, 2733\-2734 \(1964\), received 10 February 1964; identity VALIDATED\_WITH\_WARNINGS, a caption warning; first page checked\: pdf page 2, which begins with the end of another letter; pdf page 1 is the publisher's cover\)\. Page numbers are journal pages \(pdf page \+ 2731\)\. Not the full paper of Bridge and Buckingham, Proc\. R\. Soc\. A 295, 334 \(1966\), which sneep\_2005 and christiansen\_1998 cite \(not in the library\)\. WHAT IS HERE\. Table I\: 10^2 rho\_0 \(the depolarization ratio at 1 atm, 20 C\) and the anisotropy \(alpha\_par \- alpha\_perp\) \(A^3\) of Ar, Xe, SF6, H2, N2, O2, CO2 \(for a later phase\: not extracted\), and the mean polarizability alpha \(A^3\) 'calculated \(for 6328 A\) from refractive indices given in the Landolt\-Bornstein tables \(1962\)' \(p\. 2734\)\: not the authors' measurement\. These seven alpha are extracted as reproduced polarizability volumes\. CO is not in the table\. The H2 anisotropy kappa = 0\.125 \+\- 0\.005 is compared with a calculated 0\.117 \(text\)\. CHECK \(computed 2026\-09\-25\)\: against the curated fits at 632\.99 nm \(vacuum\) the alpha agree to \-0\.06 \.\.\. \+0\.3 % \(Ar \-0\.02, Xe \-0\.06, H2 \+0\.28, N2 \+0\.25, O2 \+0\.08, CO2 \+0\.06 %\) except SF6, \+0\.71 %\. alms\_1975's N2 at 6328 A \(Landolt\-Bornstein, 1\.766\) is the same source to the last digit\. STRUCTURAL FIX in the script\: the library cells lost the gas\-name column and the headings; the rows are assigned in the printed order \(image checked\)\. The depolarization cells are misread \('0\.OO5', 'Q\.OO1'\); they are not extracted\. **Recorded bibliographic identity status:** VALIDATED\_WITH\_WARNINGS. This concerns identification of the source; it does not establish the scientific correctness of its contents.
