Abstract
We present accurate new wavenumbers for a set of 13 mid-infrared fine- structure lines. The wavenumbers were determined from observations of the planetary nebula NGC 7027 and of the red supergiant alpha Scorpii. Most of the new wavenumbers are good to within 0.0025%, or 8 km s(-1) . We provide details on the measurements and present an analysis of th e errors. In addition, we present the first observations of hyperfine splitting in the [Na IV] 1106 cm(-1) line.
