A new compilation of methane line parameters for the 4136-4666-cm-1 region has been obtained using experimental positions and intensities combined with known quantum assignments from the literature. Positions and intensities measured directly from the observed spectrum by computer are reported with accuracies of ±0.0005 cm-1 and 2%, respectively, for single unblended absorptions.
