The asymptotic properties of the low-degree solar gravity modes classified by Hill and Gu are studied in the framework of first- and second-order asymptotic theory predictions. The results of this analysis demonstrate the necessity of retaining the second-order term in asymptotic theory to describe the eigenfrequency spectrum. In this theory, there are two first-order parameters, T/sub 0/ and delta, and two second-order parameters, V/sub 1/ and V/sub 2/. Values of the parameters obtained in this analysis are: T/sub 0/ = 36.31 +- 0.12 min, delta = /minus/0.43 +- 0.13, V/sub 1/ = 0.35, and V/sub 2/ = 4.76. There remain differences of approx.0.3 ..mu..Hz between the asymptotic theory eigenfrequencies and observed eigenfrequencies which are quasi-periodic functions of the radial order n for a given value of the degree /ell/. 26 refs., 1 fig., 1 tab.
