The intensity of the fluorescent radiation from the red wing of the Na D-lines perturbed by rare-gas atoms has been measured as a function of temperature and rare-gas density. These observations were then combined with a quasistatic analysis to determine the potential well depths and the emission peak wavelengths for ${\\rm Na(3P)He}\\sb2,$ ${\\rm Na(3P)Ar}\\sb2,$ ${\\rm Na(3P)Kr}\\sb2,$ and ${\\rm Na(3P)Ar}\\sb3$ molecules. The following results were obtained: for ${\\rm Na\\sp\\* He}\\sb2,$ ${\\rm D = 820(110)\\ cm}\\sp{-1},$ $\\lambda = 8400$ A; for ${\\rm Na\\sp\\* Ar}\\sb2,$ ${\\rm D = 1100(150)\\ cm}\\sp{-1},$ $\\lambda = 7200$ A; for ${\\rm Na\\sp\\* Kr}\\sb2,$ ${\\rm D = 1355(180)\\ cm}\\sp{-1},$ $\\lambda = 7400$ A; and for ${\\rm Na\\sp\\* Ar}\\sb3,$ ${\\rm D = 1595(300)\\ cm}\\sp{-1},$ $\\lambda = 8600$ A. These results are consistent with a simple model of the alkali-rare-gas molecules in which the depth of the potential energy well of a given molecule can be accurately represented as the sum of well depths of the individual alkali-rare-gas pairs.
