The problem of calculating the curves of growth (COG) of spectral lines in a comet with an isotropic gas outflow is considered; formulas are derived for primary and secondary molecules, and COG families are constructed for the variations of different parameters. The proposed approach is used to determine water-vapor production rates in Comet Halley on the basis of Vega measurements of the 2.7 and 1.38 micron H2O bands. Formulas for secondary molecules, with reference to IUE measurements of the OH 3090 A band in Comet Halley, yield an OH production rate of (0.9 + or - 0.25) x 10 to the 30th/sec.
