摘要：

In this paper a fluorescence model for cometary emission in the nu(2), nu(3), and nu(9) bands of methanol is described. This model is used in conjunction with observed spectra of several comets to determine the possible contribution of CH3OH to the frequently seen 3.4-mu-m "cometary organic" feature. For comets P/Halley and Wilson, methanol production rates are retrieved from the flux in the nu(3) band centered at approximately 3.52-mu-m.
